Registry code: b0ce321b8b47857b
Two independent observers on different networks capture your URL at the same frozen instant; matching captures are CERTIFIED, the evidence is stored permanently, and an ERC-721 certificate carrying every observer hash is minted to the wallet that paid.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address stands behind 2 doors on this origin, so the chain figures are the operator's. How it is counted.

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 reads 0.02 USDC paid never probed
GET /verify?id={token id | Arweave tx | job id}: $0.02 x402 USDC on Base. Re-downloads the permanently stored screenshot and manifest, recomputes every SHA-256, and checks them against the manifest and the on-chain record. Machine-readable verdict with per-check detail.
capture changes data 1 USDC paid never probed
POST /capture {url, mode}: $1.00 fullpage / $0.50 viewport, x402 USDC on Base. Two independent observers capture at one frozen instant; permanent Arweave storage, RFC 3161 timestamp, ERC-721 certificate minted to the paying wallet. 202 + free claim URL, ~30-120s.
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 idb0ce321b8b47857b.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/b0ce321b8b47857b/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.
