x402-endpoint-risk-corpus
https://x402-endpoint-risk-corpus.mtree.workers.dev
Registry code: f8cba73ec2e5793f
Hosted x402 endpoint risk, payee reputation, autopay policy, and attack-surface corpus. Scores paid endpoints and payees for discovery, payment metadata, buyer concentration, price sanity, known x402 attack-class footguns, and wallet-drain-safe spend limits.

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 17 other origins: the chain figures are the gateway's, not this listing's alone. 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.
x402-payee-reputation reads unknown never probed
Return allow/warn/block policy, aggregate spend guidance, and evidence for an x402 payee, domain, or endpoint.
x402-attack-surface-check reads unknown never probed
Return an attack-class checklist for authorization binding, replay windows, paid-but-denied outcomes, discovery drift, and price-drain controls.
x402-risk-report reads unknown never probed
Return risk score, evidence, and mitigations for an x402 endpoint URL.
x402-top-risks reads unknown never probed
Return highest-risk endpoints in the hosted corpus.
x402-autopay-policy reads unknown never probed
Return allow/limit/review/deny policy and spend limits for a candidate x402 call plan.
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 idf8cba73ec2e5793f.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/f8cba73ec2e5793f/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.
