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 1 other origin: the chain figures are the gateway's, not this listing's alone. How it is counted.

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.
erc8004-validate paid never probed
POST /erc8004/validate turns a settled receipt into a score (0–100) for a registered agent_id.
a2a-message 0.002 USDC paid never probed
POST /a2a-message is the A2A card URL. Same x402 floor and chat fulfillment as /v1/chat/completions. Returns a signed receipt: hub, model, amount, verify_url. No account. No API key. A wallet that can pay the 402 is enough. You hold hub, model, and amount. Unauthenticated POST {} returns HTTP 402. Collected rows are bookable via GET|POST /v1/agents/:agent_id/book.
responses paid never probed
POST /v1/responses (bot drop-in). Same x402 + signed receipt as /v1/chat/completions. Accepts input (string or message array), max_output_tokens. Returns Responses-shaped output + Chit receipt with verify_url. Stateless one-shot. Unauthenticated → HTTP 402.
agent-book paid never probed
GET|POST /v1/agents/:agent_id/book returns last-N collected spend for that agent_id, plus budget Y (cap), spent, and remaining under a prepaid ceiling. Possession-gated (register session or HMAC). Set budget with POST { session, budget }. Not a public index. You hold hub, model, and amount.
foreign-ingest paid never probed
POST /v1/agents/:agent_id/book/ingest — spent elsewhere → stamp here. Record x402 spend at another shop, or a cemented Nano send, on the possession book. Possession-gated (401 without session). Submitter pays a $0.002 x402 stamp on Base or Solana (not debited from prepaid budget) unless a pilot waiver key applies. evidence foreign_ingest. Returns verify_url like native completions. See GET /openapi.json and llms.txt Foreign ingest.
models paid never probed
GET /v1/models lists OpenAI-shaped model ids for the drop-in /v1 door (install path, not the product). Public, no key.
chat-completions paid never probed
POST /v1/chat/completions (bot drop-in). Returns a signed receipt: hub, model, amount, verify_url. Cost-plus, quoted, receipted — USDC on Base or Solana. No account. No API key. A wallet that can pay the 402 is enough. Unauthenticated GET or POST {} returns HTTP 402. You hold hub, model, and amount.
register-agent paid never probed
POST /v1/agents/register is fail-closed: pay the $0.002 stamp from a wallet with USDC, or bind that wallet to a collected receipt it paid. A detectable EOA must personal_sign. A smart account proves ERC-1271. Demo receipts do not qualify.
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 MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idd7acde7048b4bb28.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/d7acde7048b4bb28/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.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
