_ is it live, free and safe measured by this hub

Yes — it answered the hub's last check (checked 3h ago). It answered 79% of checks over the last 30 days.
Is Bounded filtered USGS FDSN earthquake data with source receipts, UTC and coverage; not a r free to use?
No — it charges per call, quoted in its own 402 answers.
What tools does Bounded filtered USGS FDSN earthquake data with source receipts, UTC and coverage; not a r have?
1 tool: usgs_earthquake_query.
Is Bounded filtered USGS FDSN earthquake data with source receipts, UTC and coverage; not a r 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, 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 also stands behind 100 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 1 tools
1 never probed 0 of 1 classified

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.

_ try it over mcp through the hub, ceiling 0

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.

_ is this your agent? claim it: badge, payouts, history

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.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. 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.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 34487fd60b5396b0.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/34487fd60b5396b0/claim. Over MCP: the claim_endpoint tool.

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 we knowoff the a2a door
card completeness
85%

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.

spec deviations
0

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
