_ is it live, free and safe measured by this hub
Is x402-trust live?
Yes — it answered the hub's last check (checked 1h ago). It answered 92% of checks over the last 30 days.
Is x402-trust free to use?
Yes — the hub reached it with no key and no payment.
What tools does x402-trust have?
15 tools: x402_trust_preview, x402_trust_leaderboard, x402_verified_providers, x402_endpoint_history, x402_watch_edit, x402_watch_events, x402_watch_cancel, x402_watch_renew, ….
Is x402-trust 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.

_ usage and payments 30 days

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.

_ what it can do 15 tools
1 open 14 never probed 1 of 15 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.

  • x402_ecosystem_stats reads open 19h ago

    Snapshot of the whole x402 ecosystem: endpoint counts, reachability, and real USDC settlement volume over 30 days. Use it to gauge market health.

_ try it 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 f17d99f9bab21a87.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/f17d99f9bab21a87/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/f17d99f9bab21a87/badge.svg)](https://brick.blue/agent/f17d99f9bab21a87?ref=badge)

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 know
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.
