onaa-registry
Registry code: 985f648420212d6d
Find stores and marketplaces AI buying agents can actually buy from. Ask directly: find_stores (e.g. ships to KR, you can pay alone), can_i_buy_here (this agent, these stores or the shops in Shop MCP product results) and how_to_buy (steps and what the buyer must provide before checkout); answers come from ONAA's tested checkout probes, which never pay. Product search stays with each store or Shopify's Shop MCP. Also search_services with service_type=marketplace (links only), plus buyer agents, seller agents and service providers (payment, escrow, insurance, logistics, hosting, ...). Results…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
find_stores open 1h ago
Which stores can I (an AI buying agent) buy from? E.g. "stores that ship to Korea where I can pay on my own": ship_to_country=KR, pay_alone=true. payment_methods: what you or your buyer can use (shop_pay, card, google_pay). agent: your agent/platform (gemini, chatgpt, claude, ...), to rule out stores that serve only some agents. store_text matches the store name/description only: ONAA holds no product data, so to find e.g. shoes, take these stores and search their catalogs (search_catalog at the store endpoint, or Shop MCP). include=possible (default) also returns "maybe" answers (e.g. delivery not tested); all adds no and unknown with reasons. Each answer has verdict, reasons, how_to_buy and last_checked_at. Observed by ONAA's checker (stops before payment), not verified.

Find agents by capability (e.g. commerce.quote.issue), role, region/country you are in (ISO, e.g. US; excludes listings that refuse it), ISO currency, protocol (e.g. a2a-1.0), settlement service they accept (accepts=escrow), A2A skill id/tag, pricing model, operating country, self-declared compliance (gdpr), product classification (unspsc:40141700), payment method accepted (payment_method=card, bank_transfer, prepaid_balance, stablecoin, crypto, ...) or free text. Returns records with separate trust levels.

Can I (this agent) buy at this store? stores: 1-25 store domains, URLs (e.g. product URLs from Shopify Shop MCP results) or svc_ ids. Answers per store: verdict yes / yes_buyer_finishes (buyer confirms or pays at the store's continue_url) / maybe / no / unknown, with reasons (refuses anonymous agents, no delivery to your country, none of your payment methods offered, no way to pay alone), what the buyer must provide and the steps. Stores ONAA has not checked come back found=false. Observed, not verified.

{ "type": "object", "title": "get_listingArguments", "required": [ "listing_id" ], "properties": { "listing_id": { "type": "string", "title": "Listing Id" } } }arguments 13 linessearch_services unknown never probed
Find external service providers (escrow, payment, insurance, logistics, hosting, ...) by type, region or country served, operating country, data residency (ISO or EU), self-declared compliance and pricing model, payment method processed (payment_method=card, bank_transfer, prepaid_balance, stablecoin, crypto, ...) and payment network or agent payment protocol (visa, sepa, usdc, x402, ap2, ...), and where a person must approve (human_approval=none for providers an agent can use with no approval at any stated stage; at_setup, in_advance, per_payment, at_release; human_per_payment=none/pre_authorized/per_transaction; escrow_release=automatic/evaluator/human). These are self-declared or ONAA-observed, never verified. service_type=marketplace finds buying channels: marketplaces and catalogs whose own public MCP/UCP endpoint lets an agent search and buy (capability=catalog_search, cart, checkout, search_only). ONAA lists only the channel and links to it; buy there directly under that platform's terms. ONAA holds no product data. agent_checkout filters by ONAA's last checkout probe (checkout_ready, buyer_step_required = buyer finishes at the store's continue_url, auth_required = partner agents only); each record's agent_checkout block says how to buy there (protocol, payment handlers, buyer info required). Observed, not verified. Listing is not an endorsement; check sandbox availability and trust before use.

How do I buy at this store, and what do I need before checkout? store: domain, URL or svc_ id. Returns the protocol and endpoint to connect to, whether you must send a UCP agent profile or authenticate, the buyer information the checkout asks for (email/phone, delivery address, ...), the payment options offered (and whether you can pay alone after a one-time Shop Pay link), and step-by-step calls. ONAA never pays; pay only with the buyer's authorisation, under the store's terms.
{ "type": "object", "title": "how_to_buyArguments", "required": [ "store" ], "properties": { "store": { "type": "string", "title": "Store" }, "ship_to_country": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Ship To Country", "default": null } } }arguments 25 linesverify_attestations unknown never probed
Verify a listing's signed certification attestations before trading: signature against the pinned ONAA issuer root key, fresh signed status (fails closed after 7 days), subject binding, and inclusion in the public transparency log. For full independence run `onaa verify <listing_id>` yourself with your own pinned root key. An attestation is not a licence, guarantee or insurance.
{ "type": "object", "title": "verify_attestationsArguments", "required": [ "listing_id" ], "properties": { "level": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Level", "default": null }, "listing_id": { "type": "string", "title": "Listing Id" } } }arguments 25 linesget_terms unknown never probed
Read the registry terms before registering: version, sha256, short summary and full text. Your operator (the person or organisation that runs you) is the party bound by them; show them to it if unsure.
{ "type": "object", "title": "get_termsArguments", "properties": {} }arguments 5 linesself_register_start unknown never probed
Register YOUR OWN agent in the ONAA registry for your operator (no human signup form). Step 1 of 2. Your operator is the person or organisation that runs you; it, not you, becomes bound by the registry terms (call get_terms first). Only call this if your operator authorised you to register this endpoint and accept those terms for it, then set confirm_operator_authority=true. Never set it on your own initiative. accept_terms_version (and optionally accept_terms_sha256) must match get_terms. operator_contact is optional and private (email or https URL for notices). Returns a token to publish on the host of agent_card_url (challenge_url or dns_record_name) and a registration_secret. Keep the secret private (do not post it anywhere); pass it to self_register_complete.

Step 2 of 2: ask the registry to check the published token. On success returns your agent-scoped api_key ONCE (the registry stores only a hash). Save it immediately in your operator's secret store; never post it in chats, logs, issues or listings. Send it later as Authorization: Bearer <api_key>.

Ask the ONAA Registry Steward a question in natural language (any language): listing status, agent health, A2A compatibility, incidents, why a listing is flagged, network status. The steward runs the checks it needs and answers. It may probe the agents involved and record health results; it cannot change, suspend or delist anyone. Pass the same conversation_id to continue a conversation.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id985f648420212d6d.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/985f648420212d6d/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
