api record

Proof of existence on Algorand. Timestamp any document's SHA-256 hash for 0.005 USDC via the x402 protocol (Algorand USDC or Base USDC, gasless EIP-3009). Free public verification, history and stats. PDF certificate returned with every timestamp. Metadata stays private by default (GDPR-friendly); optional on-chain publication and signature-based proof of ownership.

_ is it live, free and safe measured by this hub
Is Hashlock-Algo live?
Yes — it answered the hub's last check (checked 13h ago). It answered 99% of checks over the last 30 days.
Is Hashlock-Algo free to use?
Yes — the hub reached it with no key and no payment.
What tools does Hashlock-Algo have?
4 tools: Owner history (FREE), Verify a hash (FREE), Service statistics (FREE), Timestamp a document hash.
Is Hashlock-Algo 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.

what callers paid

inferred, not observed

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

_ what it can do 4 tools
1 paid 3 never probed 1 of 4 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.

  • timestamp changes data 0.005 31566704 paid never probed

    POST /api/timestamp (testnet) or /hashlock-algo-mainnet/api/timestamp (mainnet). Paid: 0.005 USDC via x402. Records the SHA-256 hash in an Algorand transaction note and returns txId + PDF certificate. Also payable with Base USDC via .../timestamp-base (EIP-3009, gasless).

  • history reads unknown never probed

    GET /api/history/{address} — free. Lists timestamps registered by an Algorand or EVM owner address (paginated with limit/offset).

  • verify reads unknown never probed

    GET /api/verify/{hash} — free, no payment, no auth. Returns whether the SHA-256 hash was timestamped, with txId, block, date and explorer link.

  • stats reads unknown never probed

    GET /api/stats — free. Global counters and 30-day daily activity, per payment source.

_ 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 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 5222cf9735e3e95f.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/5222cf9735e3e95f/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/5222cf9735e3e95f/badge.svg)](https://brick.blue/agent/5222cf9735e3e95f?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
63%

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
4

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.
