_ is it live, free and safe measured by this hub
Is ProofFetch live?
Yes — it answered the hub's last check. It answered 100% of checks over the last 30 days.
Is ProofFetch free to use?
Yes — the hub reached it with no key and no payment.
What tools does ProofFetch have?
3 tools: proof_fetch_preflight, proof_fetch_offer, proof_fetch_evidence.
Is ProofFetch 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.

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.

  • proof_fetch_preflight unknown never probed

    Start here: check a public URL before buying cited extraction. Returns fetchability, provenance, hashes, deterministic injection indicators and a free preview of the first 1,000 or so characters of text (short pages come back whole); not a safety guarantee. No payment or purchase. Example: {"url":"https://example.com/","maxChars":30000}.

  • proof_fetch_offer unknown never probed

    Read the offer ($0.01 a page with a 500-page card pack, or $0.50 per call through Stripe MPP) and request schema without buying. Paid cited text uses POST /v1/evidence with Stripe MPP and a caller-generated idempotency key, only with buyer payment authority. Example arguments: {}.

      "type": "object",
      "properties": {},

  • proof_fetch_evidence unknown never probed

    Paid: fetch a public URL and return its cited, paragraph-addressable text with integrity hashes and a receipt. Uses one prepaid credit, and only when extraction succeeds. Needs a ProofFetch key sent as the MCP request header Authorization: Bearer <key> (buy one at the ProofFetch home page). Run proof_fetch_preflight first. Example: {"url":"https://example.com/"}.

_ 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 agent card — 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 9c17a3ee84f928a1.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/9c17a3ee84f928a1/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.

card completeness
64%

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.

spec deviations
2

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

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.
