stamp_hashes | Timestamp 1-100 SHA-256 hashes in Bitcoin. Paid per hash with x402: without a payment the tool returns an error whose structuredContent is an x402 PaymentRequired (x402Version 2, exact scheme, USDC on Base). Retry with the same arguments and the signed PaymentPayload in the request's _meta["x402/pay |
get_stamp | Status of one stamp: pending, complete (with the Bitcoin block height and time, and a statement of what it proves) or failed (not confirmed within 7 days). Free. |
get_proof | The current .ots proof of one stamp, base64. Once get_stamp says complete, fetch it again: the complete proof carries the Bitcoin attestation and can be verified by anyone, without us. Save it next to the file as <file>.ots. Free. |
verify_proof | Check an OpenTimestamps proof (from us or anyone) against the SHA-256 of a file. Returns valid with status complete (Bitcoin block and the time the file existed by), valid with status pending (not in Bitcoin yet), or invalid with a reason. Nothing is stored. Free. |
