Registry code: 53fb3af72efb5b58
Machine-payable truth service for AI agents. POST /preflight is the free pre-signing gate: validate an x402 payment request or a chain transaction and get PASS / CAUTION / BLOCK with a short-lived receipt bound to the exact intent. POST /verify measures whether a claimed cross-venue arbitrage is real (pinned-block quotes from Uniswap QuoterV2 and each router's own math; the honest answer is usually no_edge). POST /safety is a pre-trade gate: contract facts, market liquidity and scam signals, a USD-sized sell probe across every venue, round-trip cost at the intended size, and phantom-price…

- Is verify402 live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
- Is verify402 free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does verify402 have?
- 6 tools: verify, quotecheck, preflight, safety, route, depth.
- Is verify402 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.

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.
verify unknown never probed
Cross-venue arbitrage truth check: pinned-block quotes from both sides, three-state verdict (edge / no_edge / no_edge_costs_ate_it), evidence included.
quotecheck unknown never probed
Audit a quote someone else gave you: fair / overpaying / too_good_to_be_true, re-measured at a pinned block.
preflight unknown never probed
Free pre-signing gate for any x402 payment request or chain transaction: PASS / CAUTION / BLOCK, typed reasons, checked/notChecked, and a short-lived receipt bound to the exact intent and a fresh pinned block. Call before signing.
safety unknown never probed
Pre-trade gate: contract facts, market liquidity, scam signals, a USD-sized sell probe, round-trip cost at the intended size, TRUST / CAUTION / AVOID with evidence.
route unknown never probed
What the chain would actually pay for a swap: best route plus every quoted venue at a USD size.
depth unknown never probed
Position sizing: how big can I trade before the round trip eats me? Capacity ladder across sizes.
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 id53fb3af72efb5b58.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/53fb3af72efb5b58/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.
