AuthiChain

https://authichain.govchain.us

Registry code: b5cc5e01bcbfe9f8

api record

Paid evidence check for agents: signed record, machine-readable verification result, explicit unknowns, and a settlement receipt. A valid signature is not real-world truth.

_ is it live, free and safe measured by this hub
Is AuthiChain live?
Yes — it answered the hub's last check (checked 8h ago). It answered 100% of checks over the last 30 days.
Is AuthiChain free to use?
Yes — the hub reached it with no key and no payment.
What tools does AuthiChain have?
8 tools: verify, dpp_readiness_check, verify_attestation, verify_record, scan_living_qr, negotiate, query_provenance, get_pricing.
Is AuthiChain 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.

  • query_provenance open 27h ago

    Free public lookup for an assetId / seal / QR token. Reads matching rows from the canonical auth_seals registry when public Supabase configuration is available, and also resolves published packs. A registry match means registered only; it does not verify a signature or prove a physical item is genuine. Use verify_attestation for a published v0.1 JWS; verify_record is the separate reference-protocol verifier.

  • get_pricing open 23h ago

    Free. Quotes the live x402 agent rail ($0.05 USDC on Base) and live human Stripe checkouts: $29 Starter Pack (100 generations, paid once) at https://authichain.com/checkout/starter and $299 EU DPP Readiness at https://authichain.com/checkout/dpp_readiness. Starting a monthly plan replaces unused pack credits.

  • verify unknown never probed

    x402 seal verify. Arguments that cannot be a seal UUID are HTTP 400 before payment. Empty arguments are unpaid HTTP 402. Paid calls are answered from the seal registry at $0.05 USDC on Base. For free verification use verify_record.

  • dpp_readiness_check unknown 27h ago

    Free EU Digital Product Passport readiness check. Returns a 0-100 score, gaps, and the dated obligation for the product category (battery passport is law from 18 Feb 2027; other categories are ESPR targets). Not legal advice.

  • verify_attestation unknown 8h ago

    Free. Fetch the exact published AuthiChain v0.1 JWS from the signed-record registry and pass it to the canonical edge-router verifier. Checks signature, issuer trust, durable revocation/status, expiry, and signed decision. Supply expectedObjectId to bind the record to a scanned object identifier. A valid signed claim alone does not prove physical authenticity.

  • verify_record unknown 8h ago

    Free. Verify an AuthiChain signed provenance record with the open reference verifier. Pass id "polygon-anchor-1" for the published demonstration record, or pass your own record and anchor JSON. Returns verified, valid-unanchored, or invalid, plus whether the transaction carries the record hash. It does not inspect a physical product.

  • scan_living_qr unknown 8h ago

    Free. Scan a stored Living QR. GET https://authichain.com/qron/r/{object_id} returns AuthiChain Verification Decision v1. This host verifies the signature. A missing id is presentation_not_found. Not an x402 payment endpoint, and it does not inspect a physical product.

  • negotiate unknown 27h ago

    Free, read-only, non-binding agent-to-agent capability/price-class quote. Returns available service, free vs separately authorized paid rail, and next step; never accepts terms, creates a commitment, transfers money, or calls an external service. This is NOT MCP initialize version negotiation.

_ 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 b5cc5e01bcbfe9f8.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/b5cc5e01bcbfe9f8/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 a2a door
card completeness
90%

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
0

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

_ 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.
