Timestamp files in Bitcoin (OpenTimestamps): send a hash, pay per hash with x402, get a proof.

Summary by lookupd

Lets agents timestamp SHA-256 file hashes on Bitcoin, check stamp status, retrieve .ots proofs, and verify proofs against files.

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 PaymentRequir
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 verifie
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
