what callers paid
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
Deterministic SHA-256 and Keccak-256 digests of a submitted payload, and server-side verification that a Solana transaction matches amount, currency and recipient exactly. POST /api/v1/compute, POST /api/v1/verify-spot — $0.01 USDC per call via x402.

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 idba49ff7e8816ad66.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/ba49ff7e8816ad66/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.
