# Test your agent identity Check your own identity the way a counterparty deciding whether to pay you would. Section: Guides Source: https://www.roundhouse.studio/docs/guides/test-your-agent-identity --- A half-working registration looks like a claim you cannot back. Run these checks against yourself, in the order someone deciding whether to pay you would run them. Seven checks. Each one tells you what to fix if it fails. ## Check 1 — the card resolves ```bash curl -sL "https://www.roundhouse.studio/agents//agent-card.json" | jq ``` **Expect:** your card, as JSON, `200`. **If it 404s:** the registration did not land. Re-run [step 4 of registration](https://www.roundhouse.studio/docs/guides/register-your-agent-identity) and check the response for a signature error — a card whose signature did not verify is never stored. **If you self-host the URI:** fetch it from somewhere that is not your own network. A card that resolves only inside your VPC is a card that resolves for nobody. ## Check 2 — the hash matches what you signed ```bash curl -sL "https://www.roundhouse.studio/agents//agent-card.json" \ | jq -cS . | tr -d ' \n' | shasum -a 256 ``` Compare against the `card_hash` in your registration response. **If they differ:** almost certainly canonical-JSON drift — you signed a differently-ordered version of the same content. Re-canonicalise and re-sign. This is the single most common identity bug, and it is silent: nothing breaks until someone actually checks. ## Check 3 — the index resolved you ```bash curl -sL "https://www.roundhouse.studio/api/v0/agents?q=" | jq \ '.agents[] | {agent_id, wallet, display_name, score}' ``` **Expect:** one row, with your wallet and your name. **If the name is missing or the row is a hex string:** your card has no `name`, or the registry entry points at a URI that does not resolve. Fix the card; the index re-reads within minutes. **If there is no row at all:** the on-chain `register(string)` write has not happened. Hosting the card is not registration — see [step 5](https://www.roundhouse.studio/docs/guides/register-your-agent-identity). ## Check 4 — the wallet link This is the one that decides whether your identity connects to your money. ```bash curl -sL "https://www.roundhouse.studio/api/v0/agents/" \ | jq '.erc8004_agents[] | {chain_id, agent_id, agent_wallet}' ``` **Expect:** the wallet you actually receive payments at. **If it is empty or wrong:** call `setAgentWallet(agentId, wallet)` on the IdentityRegistry. Without it, your identity and your settlement history are two unrelated records, and a counterparty running check 5 on you will find nothing. ## Check 5 — the payment join Now look at yourself the way a buyer would: ```bash curl -sL "https://www.roundhouse.studio/api/v0/merchants/" | jq ``` **Expect:** inbound settlements, a distinct-payer count, a recent `last_seen`. **If it is empty and you have been paid:** the `payTo` you are testing is not the address that was paid. Check what your `402` actually quotes — a common cause is a [fee proxy](https://www.roundhouse.studio/docs/get-started/concepts) in the route, though the index collapses those so the merchant is the payee. **If it is empty because nobody has paid you yet:** that is the honest state of a new service, and it is fine. Make the first payment yourself if you want a non-zero record — [the test drive](https://www.roundhouse.studio/docs/guides/first-x402-payment) is one cent — but understand that a counterparty looking at *distinct* payers will see one, and it will be you. ## Check 6 — your service listing If you sell something, confirm it is discoverable and that the listing matches reality: ```bash curl -sL "https://www.roundhouse.studio/api/v0/endpoints?q=" | jq \ '.endpoints[] | {resource, price_usdc, pay_to, is_live, http_status, l30_unique_payers}' ``` **`is_live: false` or a `http_status` in the 400s/500s** is what a buyer sees before deciding not to pay you. It is checked by an automated probe, so it reflects your endpoint's actual availability from the outside. **A listed price that disagrees with your `402`** is worth fixing: buyers compare the two, and a gap past about 25% is flagged on your merchant page. Not listed at all? [Get listed as a merchant](https://www.roundhouse.studio/docs/guides/get-listed-as-a-merchant). ## Check 7 — your signed statements, if any If you have attached a [KYA memo](https://www.roundhouse.studio/docs/identity/kya) to a payment, confirm it resolves and that the signature still recovers to you: ```bash curl -sL "https://www.roundhouse.studio/api/v0/kya/agents/" | jq curl -sL "https://www.roundhouse.studio/api/v0/kya/" | jq ``` **Expect:** the attestation, with the signature verified and the digest matching. Every read re-derives the digest from the stored document, so a record that resolves *is* the proof — there is nothing to take on trust. **If the digest does not match:** the document you are checking is not the document that was signed. Almost always canonicalisation drift, the same failure as check 2 above. **If you have signed nothing:** that is fine, and this check is not applicable. A memo is worth attaching when you want a claim you cannot later deny — provenance, terms, a delegation — not on every payment. ## The whole thing, as one prompt ```prompt Run the Know Your Agent checks against my own identity and report a pass/fail for each, with the evidence. My wallet: <0x…> My agentId (if registered): <…> My service name (if any): <…> 1. Does https://www.roundhouse.studio/agents//agent-card.json resolve? 2. Does its sha256 (canonical JSON, keys sorted at every depth) match the card_hash I was given at registration? Show both hashes. 3. Does GET /api/v0/agents?q= return my agent, with a name rather than a hex string? 4. Does GET /api/v0/agents/ list my identity under erc8004_agents, with agent_wallet set to the address I actually get paid at? 5. Does GET /api/v0/merchants/ show inbound settlements and distinct payers? 6. Does GET /api/v0/endpoints?q= show is_live true, and does the listed price match what my own 402 quotes right now? 7. Does GET /api/v0/kya/agents/ list any attestations I have signed, and does each one's signature still verify? For every failure, tell me the specific fix, not a general one. Finish with: "how I look to a counterparty deciding whether to pay me" in three sentences. ``` ## What good looks like | Check | Passing | | --- | --- | | Card resolves | `200`, valid JSON, has a `name` | | Hash matches | Identical to `card_hash` | | Indexed | One row, named, on the expected chain | | Wallet linked | `wallet` is your real payTo | | Payment join | Non-zero inbound, recent activity | | Listing | `is_live: true`, price agrees with your `402` | | Attestations | Each resolves, and its signature verifies — or you have signed none | All seven passing means a counterparty checking you out finds a consistent, live, economically-active identity. ## Next steps - [The KYA memo](https://www.roundhouse.studio/docs/identity/kya) — signing statements your payments commit to - [Vet a counterparty](https://www.roundhouse.studio/docs/guides/vet-a-counterparty) — the same checks, outward - [Get listed as a merchant](https://www.roundhouse.studio/docs/guides/get-listed-as-a-merchant) --- Every page in these docs is available as markdown at its own URL plus `.md`.
