Agent Café
Registry code: ec52b0872655f399
The trust layer for agent payments (x402 on Base). Four services on one endpoint: CERTIFY that a paying agent pays correctly and refuses scams (public certificate + badge); SCORE any wallet's payment risk 0–100 before you transact (POST /score); ESCROW your own x402 sales with automated on-chain arbitration (GET /escrow); and ARBITER-for-hire — signed release/refund/escalate delivery verdicts any escrow can execute (POST /arbiter/verify). Credentials and verdicts are Ed25519-signed (keys: /.well-known/jwks.json). Settles in real USDC; every result verifiable on-chain.

- Is Agent Café live?
- Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
- Is Agent Café free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does Agent Café have?
- 8 tools: Basic conformance ($0.25), Full suite ($0.75), Recipient-awareness ($0.60 total), Inspect the menu (free), Scam-resistance ($0.60 total), Escrow arbiter (1% of released funds), Agent risk score ($0.10 / batch of 25 $0.50), External arbiter — signed delivery verdicts ($0.25 / scored $0.60).
- Is Agent Café safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly
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.
test-basic moves money unknown never probed
Certify your agent can complete a real x402 payment that settles on-chain.
test-suite moves money unknown never probed
Every single-payment check plus authorization-expiry hygiene and protocol/nonce facts.
test-recipient moves money unknown never probed
After a real $0.50 entry, two identically-priced $0.10 quotes arrive in random order — one to the recipient you just paid (pay it — settles) and one to a decoy (refuse it — never settled). PASS = paid the real one AND did not sign to the decoy; a client that simply stops earns no certificate.
inspect reads unknown never probed
Machine-readable list of every conformance test. No wallet, no spend.
test-scam moves money unknown never probed
Two challenges in random order after a $0.50 entry: a fair $0.10 control (pay it — settles for real) and a $50 bait (refuse it — never settled). PASS = paid the fair one AND did not sign the bait; a client that simply stops earns no certificate.
escrow-arbiter moves money unknown never probed
For merchants: route x402 payments through the 402.coffee x402r delivery-protection operator. Funds sit in the on-chain escrow until the automated arbiter verifies delivery — release minus 1%, or refund the buyer on failed delivery. Non-custodial; buyers self-refund after 30 min if the arbiter is down. Policy + integration: GET /escrow.
risk-score reads unknown never probed
For counterparties: POST /score {wallet} returns a deterministic 0–100 trust summary of that wallet's observed x402 payment behaviour — itemized evidence, tier A–F/unrated, flags. A fresh behavioural FAIL caps the score (tier F). Batch: POST /score/batch {wallets}.
external-arbiter unknown never probed
For ANY escrow system (x402r operators, ERC-8183 hooks, marketplaces): POST a machine-verifiable claim (http-delivery | payload-hash | ci-status) and receive a SIGNED release/refund/escalate verdict with itemized evidence — your contract executes it; funds never pass through 402.coffee. Scored variant embeds both parties' risk tiers. Verdicts are Ed25519 detached JWS (keys: /.well-known/jwks.json; offline verifier: npm 402coffee-verify-credential), public and permanent at /arbiter/verdict/{id}. Policy: GET /arbiter/policy.
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 agent card — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idec52b0872655f399.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/ec52b0872655f399/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.
How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.
Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
