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. A pending proof whose calendars have since committed it comes back complete with `upgraded: true` and the completed proof in `ots` (base64): save it in place of the pending one. Nothing is stored. Free.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed. How it is computed.

get_proofread-only | 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. |
get_stampread-only | 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. |
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/payment"] (the x402 MCP transport), or, if your client cannot set _meta, in the `payment` argument. The settlement comes back in _meta["x402/payment-response"]. Returns a batch with, per hash, the stamp id, a pending .ots proof (base64: save it now) and its ots_url, plus a receipt signed by us. Invalid input is never charged; retrying with the same payment and arguments returns the same answer without paying twice. |
verify_proofread-only | 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. A pending proof whose calendars have since committed it comes back complete with `upgraded: true` and the completed proof in `ots` (base64): save it in place of the pending one. Nothing is stored.
