Registry code: b251734d4e8fa623
Non-custodial routing and audit layer on top of x402. Ed25519-signed receipts with on-chain settlement evidence, verifiable offline. Fail-safe paywall on Base via the Coinbase CDP facilitator. Verifier on npm: [`@trustbench/verify-receipt`](https://www.npmjs.com/package/@trustbench/verify-receipt).

- Is trustbench live?
- Yes — it answered the hub's last check (checked 46m ago). It answered 99% of checks over the last 30 days.
- Is trustbench free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does trustbench have?
- 3 tools: verify_receipt, get_rankings, get_receipt.
- Is trustbench 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. Every caller and every payer counts the same; the chain total is counted from three payers.

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.

Verify the Ed25519 signature on a TrustBench receipt. Two modes: (1) Lookup mode — pass receipt_id and the server fetches the receipt from trustbench.io and re-runs verification (handy when you only have an ID). (2) Offline mode — pass receipt_json (the full {receipt, signature} envelope an agent received from a third party) and the server verifies the Ed25519 signature against the published public key at trustbench.io/.well-known/trustbench-pubkey without trusting the database. Exactly one of receipt_id or receipt_json must be provided. Output: returns JSON with receipt_id, signature_valid (boolean), on_chain_verified (boolean, where present), signature_alg ("ed25519"), verify_url, pubkey_url. For non-server-mediated verification with no network round-trip, use the @trustbench/verify-receipt npm package.

Get TrustBench liveness rankings for x402 providers by capability. Returns a scored list of providers with latency and success-rate telemetry. Methodology note: scores are derived from HEAD-probe liveness checks (3 samples from one host), not a rigorous benchmark. See trustbench.io/methodology. Output: returns a JSON array. Each object has name (string, provider name), score (number 0-100, composite liveness score), latency_p50 (number, ms), success_rate (number 0.0-1.0, last 7 days), endpoint (string, URL), capabilities (array of strings).

Fetch a TrustBench routing receipt by ID. Receipts are immutable, Ed25519-signed records of a routing or payment event. Use to verify what was paid, to whom, for what capability, and what the on-chain settlement reference is. IDs start with rcpt_ (Phase 3) or rrcpt_ (Phase 4). Output: returns the signed receipt envelope as JSON. Phase 3 (rcpt_) returns a SignedReceipt with receipt (call metadata + settlement ref) and signature (Ed25519 over JCS-canonicalized receipt body). Phase 4 (rrcpt_) returns {receipt, signature} where receipt.paid contains routing details and signature covers the canonical envelope. To verify an envelope offline use the verify_receipt tool with the returned JSON, or @trustbench/verify-receipt npm.

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 idb251734d4e8fa623.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/b251734d4e8fa623/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.
