- Is Obol live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 95% of checks over the last 30 days.
- Is Obol free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does Obol have?
- 20 tools: Kraken top-of-book snapshot, Bitcoin address cluster, Bitcoin Cash address cluster, Cardano transaction, Base address snapshot, Kraken candles, Latest Kraken BTC/USD candle, Multi-exchange top-of-book snapshot, ….
- Is Obol 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 stands behind 20 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.

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 idd24b68daafce9106.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/d24b68daafce9106/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 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.
