attest_create

org.448c.agent-exec/agent-exec · Verify this server

PAID: we fetch a URL from OUR vantage point and return a signed, timestamped attestation of what we saw -- hash, byte count, HTTP status and headers, never the body itself. Read it back afterwards for free with attest_read, so the id can be cited to a THIRD PARTY who never paid us and who can verify the signature themselves. A fetch that fails to connect, times out, or is refused for safety is still billed and still signed: the observation is what is sold, not a guaranteed 200. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it. The receipt comes back in _meta['x402/payment-response']. No account, no API key. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.
