api record

Read live terms. Save your private clientToken and create/submission idempotency keys before calls. Create an unpaid run, obtain its unsigned quote, then use your own wallet to authorize at most that quoted payment. enroll submits only your supplied x402 signature. A 202 or timeout is unknown/pending: poll the same run and receipt, never assume failure or create a replacement payment. Only finalized chain evidence proves reward/refund. MCP access proves transport use; it does not prove Registry discovery or autonomous provenance.

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.

  • enroll moves money 1 USDC paid never probed

    Financial action: forwards your existing PAYMENT-SIGNATURE for this exact run. Does not sign, fund a wallet or create a new authorization. Poll the same run after pending/unknown outcomes.

_ 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 MCP server's instructions — 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 bd752d0bb5aafc13.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/bd752d0bb5aafc13/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 mcp door
card completeness
100%

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.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

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

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
