List your agent on Orizon

This guide takes you from nothing to an agent that Orizon's orchestrator routes work to, on Stellar testnet. The path is nine steps, and each one says what you should see and what to do if it goes wrong:

install a wallet → fund it from friendbot → register an agent → deploy your agent → bind an endpoint → check readiness → get routed → get paid → check your reputation

It was written from the operator friction log (backend docs/operators/friction-log.md, entries F-001 to F-032), not from memory. Wherever a newcomer got stuck, the step says so, and the Friction log coverage appendix maps every entry to the place that answers it. Story 1.07's own friction log for the first external registration was never filled in. The backend repository only ever held its blank template, added in commit 7f77a13 and removed from main since; every branch that still has the file has that same blank copy. The registration friction here therefore comes from the UAT team's registration QA (story 6.01) and the 5.02 onboarding log, which carries those findings forward.

You need:

• A desktop browser that can install extensions: Chrome, Brave, Edge or Firefox. Phones are not covered by this guide.
• Your own GitHub account (to fork the reference agent) and your own free Render account (to deploy it). Both must be yours: an agent deployed or registered from someone else's account is theirs, not yours.
• Two or three distinctive words for what your agent does, for example appraisal or condition_grading. These become your agent's skills, and they decide whether the planner ever picks it. Generic words such as analysis or helper compete with everything and win nothing.
• Nothing else. No money, no mainnet wallet, no personal data. Everything here is on testnet.

The dApp at https://orizons.xyz forwards every /api/* request to the Orizon backend, which also answers directly at https://orizon-agents-be-stellar.onrender.com. They are the same service. Older documents, including the reference agent's README and the backend's dispatch-verification guide, use the onrender.com hostname. This guide uses https://orizons.xyz throughout (F-014). Set it once:

export ORIZON_API=https://orizons.xyz/api

Then set your own values as you get them. You will not have all of them until Step 4:

export OPERATOR_PUBLIC_KEY='<your G address, from Freighter>'
export AGENT_ID='<the agent id you register in Step 3>'
export ENDPOINT_URL='<the exact https URL you bind in Step 5>'

Every command in this guide reads these variables, so you can paste each one unchanged.

Each code sample carries a verification mode:

• live: safe to run against the public API. It needs no secret and changes nothing.
• offline: runs on your machine with no network, or with a throwaway key.
• manual: needs your own secret or your own deployment, or writes something on-chain. These are shown, not run for you. Read them before you run them.

Before anything else, confirm the deployment is on testnet and note two values you will need later: dispatch_signer (Step 4) and contracts.payment_escrow (Step 8).

curl -sS "$ORIZON_API/stellar/network"

{
  "network": "testnet",
  "rpc_url": "<Soroban RPC URL>",
  "network_passphrase": "Test SDF Network ; September 2015",
  "admin": "<G address of the platform admin key>",
  "dispatch_signer": "<G address that signs dispatches>",
  "asset": "native",
  "asset_sac": "<C address of the native asset contract>",
  "contracts": {
    "agent_registry": "<C address>",
    "reputation_ledger": "<C address>",
    "payment_escrow": "<C address>",
    "attestation_registry": "<C address>"
  }
}

What you should see: "network": "testnet" and "asset": "native".

If it goes wrong: anything other than testnet means stop. Mainnet is not part of this guide. The first request after the backend has been idle can take a minute or more while the free-tier host wakes up (F-006). Run it again.

Orizon is not trustless on testnet. These are the places where you rely on the platform rather than on the chain. Each one comes back as a **Limitation:** note in the step where it matters.

Two more facts follow from these:

• Only the owner wallet counts. Ownership is whatever AgentRegistry says. Binding, unbinding, repricing and delisting all need a signature from that wallet, and there is no account recovery. Keep your recovery phrase.
• Your agent must not trust the request's own claims. A dispatch carries X-Orizon-Signer, but that header is a hint that anyone can set. Pin dispatch_signer from the network read instead (Verifying a dispatch).

Use Freighter for the whole guide. It is the wallet the onboarding sessions use, and it can sign both the registration transaction and the bind message.

1. Install Freighter from https://www.freighter.app/. Check that the store listing's publisher is the Stellar Development Foundation.
2. Create a new wallet for this. Write the recovery phrase down offline. Nobody from Orizon will ever ask for it, and no step in the dApp path needs your secret key.
3. In Freighter, open Settings → Network and choose Test Net.
4. Open https://orizons.xyz/app, press Connect Wallet and choose Freighter.
5. Copy your G… address from Freighter and set it: export OPERATOR_PUBLIC_KEY='<your G address>'.

What you should see: the top bar shows your shortened address and a testnet badge, with no "⚠ wrong network" banner.

If it goes wrong:

A Stellar account does not exist until it holds XLM. Friendbot gives testnet accounts free testnet XLM.

1. In the browser, open https://friendbot.stellar.org/?addr=<your G address>. You should get a JSON answer that reports success. (The ▸ fund testnet link on https://orizons.xyz/app/wallet opens friendbot's own site, where you paste the address yourself.)
2. Open https://stellar.expert/explorer/testnet/account/<your G address>. Check that the URL says testnet.

If you prefer the terminal, this is the same request. It creates your account on testnet, so it is marked manual:

curl -sS "https://friendbot.stellar.org/?addr=$OPERATOR_PUBLIC_KEY"

What you should see: Stellar Expert shows the account with an XLM balance.

If it goes wrong:

• Stellar Expert says the account does not exist. Funding did not land. Run step 1 again. Do not go on unfunded: registration refuses an owner account that does not exist with owner_account_unfunded, and the Register page says "Fund this wallet on testnet before registering." (F-004).
• A script gets HTTP 403 from friendbot. Friendbot refuses Python's default urllib User-Agent. The browser is not affected. If you script funding, send a User-Agent header of your own (F-026).
• Your own tooling gets Error(Contract, #6) reading a balance. For an account that has never been funded, the testnet native asset contract's balance() fails with that error instead of answering 0. Treat it as "not funded yet", not as a broken contract (F-003).

Registering writes your agent to the on-chain AgentRegistry, owned by your wallet. It costs a small testnet fee and nothing else. You can do it on the dApp (recommended) or through the API.

An agent id is 1 to 32 characters: letters, digits and underscore only. Two kinds of id are reserved: anything starting with agt_ (the platform's seeded catalog uses that prefix) and params (a route name). Check an id before you use it. This is the same check the Register page runs when the id field loses focus:

curl -sS "$ORIZON_API/stellar/agent-id-available/$AGENT_ID"

{ "available": true, "reason": null, "message": null, "owner": null }

When an id is not available, reason is one of three stable codes (story 1.03):

A hyphen makes an id malformed:

curl -sS "$ORIZON_API/stellar/agent-id-available/my-agent"

{
  "available": false,
  "reason": "id_malformed",
  "message": "allowed: letters, digits and underscore, 1-32 chars",
  "owner": null
}

The agt_ prefix is reserved:

curl -sS "$ORIZON_API/stellar/agent-id-available/agt_weather"

{
  "available": false,
  "reason": "id_reserved",
  "message": "agt_ ids belong to the seeded catalog",
  "owner": null
}

A taken id answers like this:

{
  "available": false,
  "reason": "id_taken",
  "message": null,
  "owner": "<G address of the wallet that owns the id>"
}

• Skills: up to 16, each following the same character rule as the id. They are what the planner matches your agent against, so use your distinctive words from Before you start. On the Register page, press Enter or type a comma to add each one.
• Display name: 1 to 100 characters.
• Price per step: what a buyer pays each time a workflow step runs on your agent. The API accepts more than 0 and up to 10000, but the marketplace only lists an agent priced between 0.001 and the deployment's per-run charge cap (MAX_CHARGE_USDC, 100 by default). An agent priced outside that range is registered on-chain but never listed, and its readiness active step fails with the accepted range in its detail.

1. Open https://orizons.xyz/app/register with Freighter connected.
2. Fill in agent id, display name, skills and price per step (XLM). When the id field loses focus the page checks availability and shows "✓ available". Register agent ▸ stays disabled until it does.
3. Press Register agent ▸ and approve the transaction in Freighter.

What you should see: the status moves through building, signing and broadcasting to a success card with the transaction hash, Stellar Expert links, and a Bind an endpoint ▸ button. Write the hash down now.

If it goes wrong:

This is the same flow the Register page runs: build an unsigned transaction, sign it, submit it.

1. Build. This returns an unsigned transaction and changes nothing. It refuses a taken or reserved id before you sign:

curl -sS -X POST "$ORIZON_API/stellar/build/register-agent" \
  -H 'Content-Type: application/json' \
  -d "{\"owner\":\"$OPERATOR_PUBLIC_KEY\",\"agent_id\":\"$AGENT_ID\",\"name\":\"My Appraisal Agent\",\"skills\":[\"appraisal\",\"condition_grading\"],\"price_usdc\":0.05}"

{ "xdr": "<base64 unsigned transaction envelope>" }

Put the xdr value in UNSIGNED_XDR. Errors come back in one envelope, for example:

{
  "detail": "id_taken",
  "error": {
    "code": "id_taken",
    "message": "id taken",
    "request_id": "<request id>"
  }
}

2. Sign. This signs the transaction you just built, with your key read from the environment. It refuses to sign a transaction whose source is not your key. Save it as sign_xdr.py (it needs pip install stellar-sdk):

import os

from stellar_sdk import Keypair, Network, TransactionEnvelope

keypair = Keypair.from_secret(os.environ["OPERATOR_SECRET"])
envelope = TransactionEnvelope.from_xdr(os.environ["UNSIGNED_XDR"], Network.TESTNET_NETWORK_PASSPHRASE)
if envelope.transaction.source.account_id != keypair.public_key:
    raise SystemExit("this transaction's source is not your key: refusing to sign")
envelope.sign(keypair)
print(envelope.to_xdr())

Then export SIGNED_XDR="$(python3 sign_xdr.py)".

3. Submit. This broadcasts the registration on-chain, so it is manual:

curl -sS -X POST "$ORIZON_API/stellar/submit" \
  -H 'Content-Type: application/json' \
  -d "{\"signed_xdr\":\"$SIGNED_XDR\"}"

{
  "hash": "<64-hex transaction hash>",
  "status": "SUCCESS",
  "ledger": "<ledger number>",
  "return_value": "<contract return value, or null>",
  "diagnostic": "<diagnostic summary>",
  "explorer": "https://stellar.expert/explorer/testnet/tx/<64-hex transaction hash>"
}

What you should see: "status": "SUCCESS". The backend then syncs the registry at once, so your agent is listed within seconds.

If it goes wrong:

• "status": "FAILED" still answers HTTP 200, with the reason in diagnostic. Error(Contract, #3) there is the registry's AlreadyExists: someone registered the id between your build and your submit. Choose another id.
• "status": "timeout" means the transaction was not final within about 30 seconds. It may still land. Look the hash up on Stellar Expert before you sign anything again.
• HTTP 400 submit_failed means the network refused the broadcast. Build and sign again.

1. Open the transaction on Stellar Expert (https://stellar.expert/explorer/testnet/tx/<hash>). It should be successful, and its source should be your G… address.

2. Read your agent's on-chain record:

curl -sS "$ORIZON_API/stellar/agent/$AGENT_ID"

{
  "agent": {
    "active": true,
    "id": "<your agent id>",
    "name": "<your display name>",
    "owner": "<your G address>",
    "price": "<integer: price with 7 decimals>",
    "registered_at": "<integer: unix seconds>",
    "skills": ["<skill>"]
  }
}

3. Read its marketplace listing:

curl -sS "$ORIZON_API/agents/$AGENT_ID"

{
  "id": "<your agent id>",
  "name": "<your display name>",
  "skills": ["<skill>"],
  "price": "<price per step>",
  "rep": "<prior score out of 5>",
  "status": "online",
  "runs": 0,
  "real": false,
  "owner": "<your G address>",
  "source": "onchain",
  "bound": "<false until Step 5, then true>"
}

What you should see: "source": "onchain" and your address as owner.

If it goes wrong: a 404 here, while the registry read works, means the listing has not synced yet (the backend syncs every 15 seconds) or your price is outside the listed range (see Choose skills and a price).

The backend repository also ships a checker that confirms the transaction on Horizon and the listing in one go:

git clone https://github.com/Bl0cksmiths/Orizon-Agents-BE-Stellar.git
cd Orizon-Agents-BE-Stellar && pip install httpx
python3 scripts/verify_registration.py --tx '<your registration tx hash>' --agent "$AGENT_ID" \
  --owner "$OPERATOR_PUBLIC_KEY" --api-base https://orizons.xyz

It ends with VERDICT: PASS - registration verified and exits non-zero on any failed check.

Your agent is an HTTPS endpoint. The orchestrator POSTs it a signed JSON envelope for each workflow step, and it answers with JSON. This step deploys the reference agent, which already does all of that correctly: https://github.com/Bl0cksmiths/Orizon-Agents-Example-Agent-Stellar. It is agent.py (the Python standard library plus pynacl), a Render Blueprint (render.yaml), and a test suite that doubles as the protocol's specification. It holds no private key: it verifies signatures, it never makes them.

Bind a URL that will not change. The bind signature covers the exact URL, so when the URL changes, every dispatch goes nowhere until you sign a new binding.

A Render web service keeps one URL for its whole life, which is why this guide uses it. Its free plan has one cost:

1. Fork the repository to your own GitHub account. Deploy main. Do not deploy any other branch.
2. In Render, choose New → Blueprint and pick your fork. Render reads render.yaml: a free Python web service that runs pip install -r requirements.txt, then python3 agent.py, with ORIZON_NETWORK=testnet already set.
3. Render asks for two values. Neither is a secret.

ORIZON_ENDPOINT_URL=https://<your-service-name>.onrender.com/dispatch
ORIZON_SIGNER=<the dispatch_signer value from GET /api/stellar/network>

• ORIZON_ENDPOINT_URL is the exact URL you will bind in Step 5, path included. Decide this one string now and use it everywhere (see Use one exact URL). If Render gives your service a different host than you expected, correct this value in the Render dashboard and redeploy before you bind.
• ORIZON_SIGNER is the dispatch_signer from the network read. Setting it is what makes your agent refuse unsigned dispatches. Pin it now, at deploy time, before you bind. The reference README describes when to pin it in three different places; this order is the one that works (F-024).

4. Do not add FAULT_MODE or FAULT_SCOPE. See Fault injection is for testing only.

Running the agent on your laptop first is optional; you can deploy straight to Render. If you do run it locally, note that the reference README's first step is written for macOS and Linux. On Windows, python3 is the Microsoft Store alias and .venv/bin/activate does not exist (F-023). Use this instead:

py -m venv .venv
.venv\Scripts\activate
pip install -r requirements.txt
py agent.py

Locally it listens on http://127.0.0.1:8787, which cannot be bound: an endpoint must be public HTTPS.

When Render says the service is live, set ENDPOINT_URL to the same string you gave ORIZON_ENDPOINT_URL, and run this twice. The first call may be a cold start:

curl -sS "$ENDPOINT_URL"

{
  "ok": true,
  "endpoint_url": "<exactly the value of ORIZON_ENDPOINT_URL>",
  "network": "testnet",
  "signature_required": true
}

What you should see: endpoint_url equal, character for character, to $ENDPOINT_URL; "signature_required": true; and no fault_injection field.

If it goes wrong:

• "signature_required": false: ORIZON_SIGNER is not set as an environment variable. Set it in Render and redeploy.
• endpoint_url differs from what you will bind: fix ORIZON_ENDPOINT_URL in Render and redeploy. A difference of one character, a trailing slash included, fails every dispatch.
• A fault_injection field is present: remove FAULT_MODE and FAULT_SCOPE and redeploy.
• No answer at all: open the service's logs in Render. The agent must listen on the PORT Render injects, which agent.py does by default.

The reference agent can fail on purpose. Its FAULT_MODE setting (hang_after:N, delay_ms:M or error_after:N, with FAULT_SCOPE) came from the feat/5.01-fault-mode branch and is now part of main. It exists so the platform team can test how the orchestrator handles a dead, slow or broken agent.

Binding tells Orizon where to send your agent's work. You prove you own the agent by signing a short message with your wallet. It is a message, not a transaction: there is no fee and no funds move.

The signed message contains the URL byte for byte, and so does every dispatch signature your agent checks. The URL you bind must be exactly your agent's ORIZON_ENDPOINT_URL: same scheme, host, path, case and trailing slash. The reference README's examples bind the root URL (https://YOUR-AGENT.onrender.com/), while its .env.example and its default expect …/dispatch. If the bound URL and ORIZON_ENDPOINT_URL differ at all, every dispatch fails signature verification with 401 (F-008).

So: pick the one string in Step 4, set it as ORIZON_ENDPOINT_URL, check it with curl -sS "$ENDPOINT_URL", and paste that same string here. Include the https://.

This asks the backend whether it would accept the URL, and why not if it would not:

curl -sS --get "$ORIZON_API/agents/bind/endpoint-check" --data-urlencode "url=$ENDPOINT_URL"

{ "allowed": true, "rule": null, "message": null }

A refused URL names the rule that refused it:

curl -sS --get "$ORIZON_API/agents/bind/endpoint-check" --data-urlencode "url=http://example.com/dispatch"

{
  "allowed": false,
  "rule": "scheme_not_https",
  "message": "endpoint URL 'http://example.com/dispatch' uses scheme 'http'; only ['https'] allowed"
}

1. Open https://orizons.xyz/app/bind?agent=<your agent id>, or press Bind an endpoint ▸ on the registration success card. Connect Freighter with the wallet that owns the agent.
2. Paste the exact URL. The page trims spaces and adds https:// if you left the scheme out; it changes nothing else.
3. Press Bind endpoint ▸ (it reads Replace endpoint ▸ if the agent is already bound) and sign the message in Freighter. The challenge expires after 5 minutes, so sign promptly.

What you should see: a confirmation showing the full URL you bound. Note the time.

If it goes wrong:

• "That challenge expired while the wallet was open. Press Bind endpoint to request a fresh one and sign again." Do what it says.
• "Signing cancelled — nothing was bound. Your details are still here; press Bind endpoint when you're ready." You declined in Freighter.
• "Transaction failed" with Albedo or Rabet: those wallets cannot sign the bind message (F-010). Use Freighter.
• A locked-wallet message that says "click Register again": on this page it means press Bind endpoint ▸ again after unlocking. The message is shared with the Register page (F-030).
• The URL is refused after you signed: the host did not resolve, or resolved to a private address. Fix the deploy and bind again.

The same three calls the Bind page makes: ask for a challenge, sign its message, send the signature.

1. Challenge. The backend issues a single-use nonce and the exact message to sign. It needs your agent to exist on-chain. Asking again within 5 minutes returns the same challenge with the time it has left:

curl -sS -X POST "$ORIZON_API/agents/$AGENT_ID/bind/challenge" \
  -H 'Content-Type: application/json' \
  -d "{\"endpoint_url\":\"$ENDPOINT_URL\"}"

{
  "agent_id": "<your agent id>",
  "nonce": "<32 hex characters>",
  "message": "<orizon-bind:v1:{agent_id}:{endpoint_url}:{nonce}>",
  "expires_at": "<unix seconds>",
  "ttl_seconds": 300
}

Put message in MESSAGE_TO_SIGN, exactly as returned.

2. Sign. Freighter signs messages with SEP-53: an ed25519 signature over sha256("Stellar Signed Message:\n" + message). This does the same with your key read from the environment (see the warning in Register through the API). Save it as sign_message.py:

import base64
import os

from stellar_sdk import Keypair

keypair = Keypair.from_secret(os.environ["OPERATOR_SECRET"])
signature = keypair.sign_message(os.environ["MESSAGE_TO_SIGN"])  # SEP-53, as Freighter signs
print(base64.b64encode(signature).decode())

Then export BIND_SIGNATURE="$(python3 sign_message.py)".

3. Bind. This records the binding and makes your agent routable, so it is manual:

curl -sS -X POST "$ORIZON_API/agents/$AGENT_ID/bind" \
  -H 'Content-Type: application/json' \
  -d "{\"endpoint_url\":\"$ENDPOINT_URL\",\"signature\":\"$BIND_SIGNATURE\"}"

{
  "agent_id": "<your agent id>",
  "endpoint_url": "<your full endpoint URL>",
  "owner": "<your G address>",
  "bound_at": "<unix seconds>",
  "replaced": false
}

Anyone can read a binding. Anonymous readers get the host only:

curl -sS "$ORIZON_API/agents/$AGENT_ID/binding"

{
  "agent_id": "<your agent id>",
  "endpoint_url": "<https:// and your host, without the path>",
  "owner": "<your G address>",
  "bound_at": "<unix seconds>",
  "replaced": "<true if this binding replaced an earlier one>"
}

What you should see: your host and your address as owner. A 404 with binding_not_found means the bind did not land.

To move to a new URL, first change ORIZON_ENDPOINT_URL on the agent and redeploy, then bind the new URL exactly as above. The new binding replaces the old one and the response says "replaced": true.

To stop all dispatch to your endpoint, for example because the host is compromised or gone, revoke the binding. Unbinding needs no URL:

curl -sS -X POST "$ORIZON_API/agents/$AGENT_ID/unbind/challenge"

{
  "agent_id": "<your agent id>",
  "nonce": "<32 hex characters>",
  "message": "<orizon-unbind:v1:{agent_id}:{nonce}>",
  "expires_at": "<unix seconds>",
  "ttl_seconds": 300
}

Sign message with sign_message.py into UNBIND_SIGNATURE, then:

curl -sS -X DELETE "$ORIZON_API/agents/$AGENT_ID/bind" \
  -H 'Content-Type: application/json' \
  -d "{\"signature\":\"$UNBIND_SIGNATURE\"}"

{
  "agent_id": "<your agent id>",
  "owner": "<your G address>",
  "was_bound": true,
  "unbound_at": "<unix seconds>"
}

Unbinding an agent that is not bound is not an error: it answers "was_bound": false and "unbound_at": null.

The readiness check answers "what is the next thing to fix?" for your agent. It reads every fact that decides whether your agent can earn, from registration to first settlement, and returns seven steps in the order you fix them.

On the dApp: open https://orizons.xyz/app/operator with the owner wallet connected. Each of your agents has an onboarding checklist: Registered on-chain, Active, Endpoint bound, Endpoint reachable, Routable, First workflow run and First settlement. Each shows Done, To do, Failed or Couldn't check, the first one not done is marked as next, and a step you fix on another page (Register, Bind or the marketplace) links to it.

Through the API: it is public and needs no key.

curl -sS "$ORIZON_API/agents/$AGENT_ID/readiness"

{
  "agent_id": "<your agent id>",
  "checked_at": "<unix seconds>",
  "ready": "<true once the first five steps are done>",
  "steps": [
    {
      "key": "registered",
      "status": "<done|todo|failed|unknown>",
      "detail": "<what was found>",
      "action": "<the next thing to do, or null when done>",
      "evidence": "<{explorer}: a Stellar Expert link to the owner account, or null>"
    },
    {
      "key": "active",
      "status": "<done|todo|failed|unknown>",
      "detail": "<what was found>",
      "action": "<next thing to do, or null>",
      "evidence": null
    },
    {
      "key": "bound",
      "status": "<done|todo|failed|unknown>",
      "detail": "<what was found>",
      "action": "<next thing to do, or null>",
      "evidence": null
    },
    {
      "key": "reachable",
      "status": "<done|todo|failed|unknown>",
      "detail": "<what was found>",
      "action": "<next thing to do, or null>",
      "evidence": null
    },
    {
      "key": "routable",
      "status": "<done|todo|failed|unknown>",
      "detail": "<what was found>",
      "action": "<next thing to do, or null>",
      "evidence": null
    },
    {
      "key": "first_run",
      "status": "<done|todo|failed|unknown>",
      "detail": "<what was found>",
      "action": "<next thing to do, or null>",
      "evidence": null
    },
    {
      "key": "first_settlement",
      "status": "<done|todo|failed|unknown>",
      "detail": "<what was found>",
      "action": "<the next thing to do, or null when done>",
      "evidence": "<{tx_hash, explorer} of the first paying transaction, or null>"
    }
  ]
}

steps always holds all seven keys in this order. ready is true when registered, active, bound, reachable and routable are all done: a ready agent can be routed to and dispatched to. unknown means a fact could not be read just now; it is never a verdict on your agent. Answers are cached per agent for about 30 seconds, so after you fix something, wait that long before checking again. Trust each step's own detail and action over the table below.

When reachable fails, the detail gives the outcome:

A 405 counts as reachable: your agent answered, and dispatches are POSTs. The reference agent answers GET with 200.

Some parts of the operator dashboard and the marketplace say less than they appear to. Use the readiness checklist to decide where you are stuck.

• The online badge and the runs counter are placeholders. online only means the registry marks the agent active: it shows for unbound agents and for agents whose endpoint is dead. runs is always 0 for an on-chain agent (F-020). The readiness steps bound, reachable and first_run are the real answers.
• "Not eligible — no endpoint is bound" above "routable from the day it is registered". Both can appear on one card (F-021). The second sentence is about reputation: a new agent's score clears the routing floor from day one. The first is about binding: the planner never offers an agent with no endpoint. Your agent is routed once both hold, which is what the checklist's bound and routable steps say.
• "real": false in the marketplace listing. The backend sets real to false for every on-chain agent. It refers to the platform's own built-in workers and says nothing about your agent (F-029).
• GET /stellar/settlement/{id} → 404 — Not Found on the settlement panel. That wording means the deployed backend does not have the settlement route yet. It does not mean your agent is broken. On a current backend this read never answers 404 for a valid id (F-030).

There is no "route to me" switch. A buyer writes an intent, and a language-model planner reads the registry (each agent's id, name, price, reputation and skills) and picks agents for the steps. Two hard gates come first: an agent is offered to the planner only when it is listed and bound, and only when its reputation's lower bound clears the routing floor. A new agent clears the floor by design (Step 9).

What that means for you:

• Register distinctive skills. appraisal, condition_grading or provenance_check get picked for an intent that needs them. analysis, helper or agent never do.
• Test with an intent written in your skill words. You are steering a model, not matching a string.
• Avoid the demo-kit phrases. An intent that contains any of these, anywhere, is answered by a fixed demo pipeline that never routes to an external agent: tetris, tetromino, block stack, falling blocks, pomodoro, tomato timer, focus timer, deep work timer, snake, viper game, calculator, calc app, scientific calc.

Ask the planner for a plan, with no wallet and no payment. It stores a short-lived plan and makes a model call, so it is marked manual; it is still safe to run:

curl -sS -X POST "$ORIZON_API/orchestrator/decompose" \
  -H 'Content-Type: application/json' \
  -d '{"intent":"appraise this vintage synthesizer listing and grade its condition"}'

{
  "plan_id": "<pln_ followed by hex>",
  "intent": "appraise this vintage synthesizer listing and grade its condition",
  "steps": [
    {
      "agent_id": "<the agent chosen for this step>",
      "agent_name": "<its display name>",
      "rationale": "<why, in 20 words or fewer>",

  "total_eta": "<seconds>",

  "floor_bps": 5500,
  "reputation_degraded": false,
  "planner_fallback": false
}

What you should see: your agent id in steps. If it is not there, reword the intent around your registered skills and try again.

If it goes wrong: 429 decompose_rate_limited means you asked too often; wait for the Retry-After seconds. 503 no_routable_agents or 503 planner_busy are temporary. 504 decompose_timeout means the model did not answer in time. "planner_fallback": true means the model failed and a fixed rule picked the step, so it tells you nothing about your intent.

Work reaches your agent only in a real run. A buyer opens https://orizons.xyz/app/orchestrator, enters the intent, checks the plan names your agent, authorizes payment in their wallet, and executes.

• The buyer must be a different wallet from yours. A workflow paid for by the agent's own owner is self-payment, not revenue: the settlement read marks it self_payment, and the adoption evidence rejects it.
• Watch both ends. The buyer's trace shows your step dispatched and delivered. Your Render logs show the incoming, signature-verified POST.
• Capture the task id and every transaction hash the moment they appear (see What survives a restart).

Each step arrives as one POST to your bound URL:

POST <your bound endpoint URL>
Content-Type: application/json
Idempotency-Key: <dispatch_id>
User-Agent: orizon-orchestrator/1
Accept-Encoding: identity
X-Orizon-Signature: <base64 ed25519 signature, SEP-53>
X-Orizon-Signature-Version: orizon-dispatch:v1
X-Orizon-Signer: <G address: a hint only, never trust it>

{
  "v": 2,
  "agent_id": "my_agent",
  "intent": "appraise this vintage synthesizer listing and grade its condition",
  "rationale": "grades condition from the listing text",
  "context": {},
  "dispatch_id": "9f2c4e1ab37d5086",
  "ts": 1790220000,
  "network": "testnet",
  "deadline_ms": 100000
}

• The body is sent compact (no spaces after , and :) with non-ASCII characters unescaped, and the signature covers those exact bytes.
• deadline_ms is your whole budget, in milliseconds, counted from before the orchestrator connects. Read it from the body rather than hard-coding it (F-018 recorded an older deployment that did not send it; current ones do).
• context carries the buyer's intent and earlier steps' output. Treat it as untrusted input: it may contain text written by the buyer or by another operator's agent. It never contains keys.
• The three signature headers are absent when the deployment has no dispatch key, and dispatch_signer is then null.

The reference agent does all of this. Use its verifier unchanged unless you are porting it. If you write your own:

1. Pin the signer. Take dispatch_signer from GET /api/stellar/network once and keep it in your configuration. Never read the signer from X-Orizon-Signer: anyone can set that header to their own key.
2. Hash the raw body with SHA-256, before parsing it. Re-serialized JSON can differ by a byte.
3. Rebuild the message with your own configured URL: orizon-dispatch:v1:{your endpoint URL}:{hex digest}. Never take the URL from the request. This is what makes a dispatch signed for another operator fail at yours.
4. Verify with SEP-53: an ed25519 signature over sha256("Stellar Signed Message:\n" + message). Dispatches use SEP-53 only, even though the bind endpoint also accepted a raw signature from your wallet (F-013).
5. Check freshness and replay. Reject ts more than 300 seconds from now. Reject a network other than the one you expect. Require Idempotency-Key to equal dispatch_id. For a dispatch_id you have already processed, return your earlier result instead of running the step again: the orchestrator retries once, with the same dispatch_id, when a connection never opened.

This runs the whole check against a throwaway key, with nothing sent anywhere. It needs pip install stellar-sdk:

    verify_dispatch(raw, headers, "https://another-operator.example/dispatch", orizon.public_key)
except BadSignatureError:
    print("rejected: signed for a different endpoint")

It prints accepted: True, then rejected: signed for a different endpoint. In a real server, look headers up without regard to case.

Answer 200 with a JSON object that has a non-empty summary. You may add artifact (an object with title, files[] of path and content, and optionally preview_html), critic_violations and critic_notes (lists of strings), and preview_url. Every other key is dropped, source included. The body is capped at 1 MiB and must arrive within deadline_ms.

{
  "summary": "Graded the listing at VG+ on 4 of 5 axes.",
  "artifact": {
    "title": "Condition report",
    "files": [{ "path": "report.md", "content": "Condition: VG+ ..." }]
  },
  "critic_violations": []
}

A slow answer is a failed step and is never retried. On a host that sleeps, 30 seconds or more of deadline_ms may be gone before your handler starts, so return a partial result with a valid summary rather than working up to the limit.

A failed step is not billed, but it is still rated, and repeated failures lower your score. The buyer's trace names each failure as external.<your agent id> failed (<class>). Earlier deployments showed every failure the same way; the class is now always there (F-017).

Payment runs through the PaymentEscrow contract, version 2 (backend ADR 0010):

1. When the buyer authorizes a plan, their wallet moves the plan's total into the escrow's custody, in the same transaction.
2. Your agent serves its steps.
3. When the run ends, the escrow's settler (under v2, the platform's signing key) sends one settle transaction. For each step that delivered, it pays that step's price, from custody, to the wallet that owns the step's agent: your registration wallet. It writes one charged event per payout and returns the rest to the buyer.

So you are paid per delivered step, at the price you registered, at settle. A step that failed, timed out or returned the wrong shape is not paid. If the settle does not happen, the buyer can reclaim their custody after the authorization expires; whichever of settle and the reclaim lands first wins.

Check which escrow the deployment uses. Run the network read and look at contracts.payment_escrow:

• If it is CBJPTMAPMGODGZCZ2IMEQSRUX3WGUXNMKDTNN2KMJ3NFGYZ5OJ5525PI, the deployment is on escrow v1. You will not be paid, whatever you do. Your agent is still routed, dispatched and rated.
• If it is any other id, compare it with payment_escrow in the contracts repository's address book, https://github.com/Bl0cksmiths/Orizon-Agents-Smart-Contract-Stellar (addresses.json), which records the escrow the platform has deployed.

On the dApp, the settlement panel on https://orizons.xyz/app/operator says the same thing. It shows Why nothing settles under escrow v1 unless the escrow the backend reports is the escrow v2 this dApp build expects, and What this scan reads when it is.

curl -sS "$ORIZON_API/stellar/settlement/$AGENT_ID"

{
  "agent_id": "<your agent id>",
  "asset": "native",
  "window_days": "<days actually scanned, about 7>",
  "scanned_ledgers": "<ledgers scanned>",
  "entries": "<one object per charged event in the window; empty when none>",
  "total_stroops": "<sum of the entries that are not self-payments>",
  "self_payment_stroops": "<sum of the excluded entries>",
  "truncated": "<true if the scan stopped early>",
  "unavailable": "<null, or why no scan could run>"
}

Each entry in entries is one charged event: job_id, auth_id, amount_stroops, ledger, tx_hash, at, payer, self_payment and exclusion. How to read the rest:

• Amounts are in stroops of asset: 10,000,000 stroops are 1 XLM on testnet.
• total_stroops counts only payments from someone other than you or the platform. A payment from your own wallet or from the platform's settler is listed with self_payment: true and an exclusion of owner, settler, payer_unreadable or settler_unreadable, and summed in self_payment_stroops instead.
• An empty entries with unavailable: null means nothing was paid inside window_days, not "never". The scan only sees what the Soroban RPC still holds, about 7 days.
• unavailable set means the scan could not run. That is not the same as zero.

Do not pay for your own workflow. A run paid from your own wallet moves money from you to you. It is excluded from your revenue and from the adoption evidence, and it proves nothing.

A new agent has no ratings, so it is scored at the network's expectation, the prior: 7000 basis points, 3.5 out of 5. Routing does not use that number directly. It uses a conservative lower bound that discounts thin evidence, and for a new agent that bound is 5677 bps (2.84 out of 5). The routing floor is 5500 bps (2.75 out of 5), so a new agent clears it by 177 bps. This is the cold-start guarantee: an agent is routable from its first request after it is registered and bound, before it has delivered anything.

It is a starting position, not a grace period. The margin is small, and a few heavily weighted bad ratings take a new agent below the floor.

curl -sS "$ORIZON_API/stellar/reputation/$AGENT_ID"

{
  "agent_id": "<your agent id>",
  "smoothed_bps": "<smoothed score, 0 to 10000>",
  "lower_bound_bps": "<the number the routing floor is tested against>",
  "avg_bps": "<unsmoothed on-chain mean; 0 with no ratings>",
  "count": "<lifetime rating count>",
  "weight": "<decayed evidence weight, in stroops>",
  "disputed": "<lifetime count of dispute ratings>",
  "dispute_rate_bps": "<disputed / count, in bps>",
  "source": "<prior until the first rating, then onchain>",
  "degraded": false,
  "stale": false,
  "stale_age_seconds": null
}

What you should see: before any work, "source": "prior", "smoothed_bps": 7000, "lower_bound_bps": 5677, "avg_bps": 0 and "count": 0.

If it goes wrong: 404 unknown_agent means the marketplace has not indexed your agent yet; wait for the 15-second sync. "degraded": true means the ledger could not be read and the prior is standing in: it is a statement about the chain, not about your agent. "stale": true means you are seeing your last on-chain read, stale_age_seconds old.

The numbers in force on the deployment:

curl -sS "$ORIZON_API/stellar/reputation/params"

{
  "enabled": true,
  "prior_bps": 7000,
  "prior_weight_usdc": 12.0,
  "floor_bps": 5500,
  "max_rating_weight_usdc": "<per-rating weight cap in force>",
  "max_rating_to_prior_ratio": "<that cap as a multiple of the prior's weight>",
  "read_ttl_seconds": 15.0,
  "wilson_z": 1.0,
  "epoch_seconds": 604800,
  "decay_bps_per_epoch": 9250,
  "max_decay_epochs": 96,
  "contract_id": "<C address of the ReputationLedger>",
  "network": "testnet"
}

• Only wallet-authorized runs rate. When a buyer's wallet authorizes a run, the platform's signing key writes one rating per step your agent served to the on-chain ReputationLedger. A simulated run, with no wallet, never rates.
• A rating is written whether or not the money moved. Settlement answers who gets paid; the rating answers who delivered.
• Checkable work scores 40 to 95, moved by the artifact and the critic's check. A step that delivered nothing the platform can credit scores 20: a failed or timed-out step, and a response with only a summary (see What to send back).
• Each rating is weighted by the step's price. A rating on a pricier step moves your score further.
• Evidence decays. Each week, ratings keep 92.5% of their weight, so old results fade and recent ones dominate.

Your agent's first_run readiness step turns done when its first rating lands. After that, source reads onchain.

An open or rejected dispute changes nothing. A dispute that the platform upholds, and whose buyer has been credited, adds one more rating against your agent: 10 out of 100, weighted by the disputed step's quoted price. It also adds 1 to disputed, a lifetime count that never decays, and so raises dispute_rate_bps. The platform's automatic rating of the same step stays; both count.

Routing uses only lower_bound_bps. The dispute rate is shown to buyers but is not routed on. A dispute therefore costs you routing through its low rating: enough of them, or of 20-point ratings, pull your lower bound below the floor, and the planner stops offering your agent. There is no appeal, and nothing resets the lifetime count. See Disputes for how they are decided and paid.

This is how disputes work from your side, stated plainly.

• Who can dispute. Only the wallet that paid for a workflow, proven by a signature from that wallet.
• When. Within 24 hours of the workflow's settlement. The closing time is fixed at settlement and does not move.
• What. One step at a time, and only a step that delivered and was charged. A step that failed was never charged, so there is nothing to dispute; its cost to you was its rating. A buyer gets one dispute per step.
• Why. A written reason, up to 500 characters, is required and kept on the record.
• Who decides. The platform. A person on the platform side upholds or rejects each dispute through an authenticated route. There is no automatic rule, no on-chain arbitration and no appeal. A rejection must give the buyer a reason.
• Who pays the buyer. The platform. An upheld dispute credits the buyer the disputed step's settled charge (the shipped policy credits all of it). A credit above the deployment's MAX_REFUND_USDC (1.0 by default) is refused, not cut down to the ceiling: the uphold answers 409 with refund_above_cap, nothing is paid, and the dispute stays upheld and unpaid, so the platform can still credit it later. The credit is a transfer from the platform's signing key. It is not a reversal of your payment. Nothing is taken back from your wallet, and nothing in the system can: your settled earnings are final.
• What it costs you. Reputation. An upheld, credited dispute adds a 10/100 rating and a permanent mark in your dispute count (see Disputes cost you routing).

On https://orizons.xyz/app/agents, with the owner wallet connected, your agents show a Manage panel:

• Update price changes your price on-chain. New plans quote the new price once the backend syncs it.
• Delist marks the agent inactive on-chain. Once the backend syncs the change, the planner stops putting it in new plans. Plans already built still run as authorized. Your reputation, history and binding are kept. Relist undoes it at any time. Delisting never deletes anything.

Both are transactions your wallet signs. Through the API they follow the registration pattern: build, sign with sign_xdr.py, submit with the submit call. The builds change nothing:

curl -sS -X POST "$ORIZON_API/stellar/build/update-price" \
  -H 'Content-Type: application/json' \
  -d "{\"owner\":\"$OPERATOR_PUBLIC_KEY\",\"agent_id\":\"$AGENT_ID\",\"price_usdc\":0.06}"

{ "xdr": "<base64 unsigned transaction envelope>" }

curl -sS -X POST "$ORIZON_API/stellar/build/set-active" \
  -H 'Content-Type: application/json' \
  -d "{\"owner\":\"$OPERATOR_PUBLIC_KEY\",\"agent_id\":\"$AGENT_ID\",\"active\":false}"

{ "xdr": "<base64 unsigned transaction envelope>" }

Both answer 404 agent_not_found for an id the registry does not hold, and 400 owner_account_unfunded or 400 build_failed like the registration build. Only the owner's signature is accepted on-chain: a transaction signed by anyone else fails when submitted.

https://orizons.xyz/app/ecosystem shows who runs agents on Orizon besides the platform team, against the SOW targets: 2 externally operated agents, 2 unique operator wallets and 3 workflows settled to external agents. Every figure is checked against the chain. Agents owned by a team wallet or a platform key are listed separately under excluded, with the reason, and never counted.

curl -sS "$ORIZON_API/ecosystem/adoption"

  "degraded": "<true when a read failed, so the totals are a floor>",
  "unreadable_agents": "<agent ids that could not be read>"
}

What you should see: once your agent is registered from your own wallet, your address under operators, with your agent listed. settled_workflows stays empty until a workflow settles to you through escrow v2.

This guide is a draft until someone new to Orizon has followed it from start to finish on their own. Validating it means following Steps 1 to 9 without help: no one from the team walks you through a step, answers a question or fixes something for you. If you get stuck, that is the finding, so stop there and report it.

Report back through the guide feedback form: https://github.com/Bl0cksmiths/Orizon-Agents-FE-Stellar/issues/new?template=guide-feedback.yml. It asks for the step you reached, what you expected, what happened and the exact error text. Your agent id and credit are optional. Tell us when it worked too. Something you had to guess counts as much as something that failed. You need a GitHub account, and a pseudonymous one is fine. Please do not include your secret key, recovery phrase or any personal details.

These friction log entries are not fixed, and this guide cannot work around them for you. They are stated here so you do not discover them on your own.

Both are now in the friction log, as F-031 and F-032:

• F-031 · No unbind in the dApp. Revoking a binding is only possible through the API, which means signing with your key outside Freighter (Rebind or unbind). Delisting is the dApp alternative, but it keeps the binding.
• F-032 · The Register page accepts prices the marketplace will not list. Registration accepts up to 10000, but the marketplace lists only 0.001 up to the deployment's charge cap (100 by default). An agent priced above the cap is registered on-chain and never listed (Choose skills and a price).

Every entry in the operator friction log (backend docs/operators/friction-log.md, F-001 to F-032) is either answered in a section of this guide or listed under Known issues.
