  • create_signing_envelope Create a FreeSign envelope from a PDF SHA-256 hash. Do not send PDF bytes. The created envelope is NOT yet session-bound — the browser that opens the returned signing_url generates an ECDSA P-256 keypair locally and POSTs the public JWK to /api/envelopes/{id}/session-bind before any protected reques
  • verify_document_hash Find FreeSign receipts matching a local document SHA-256 hash.
  • get_receipt Return the envelope record (including final_pdf_sha256, final_signature_base64url, final_payload_json), per-signer signing receipts, and OpenTimestamps anchor metadata. Evidence only, never PDF bytes.
  • get_ots_proof Return the .ots proof (base64) for a given OpenTimestamps anchor on an envelope. Use the official `ots-cli` to verify offline against Bitcoin block headers. Each seal has two anchors: `kind: "byterange"` commits to the signed document, `kind: "signed_attrs"` commits to SHA-256 of the CMS SignedAttri

Evidence only, never PDF bytes. The raw events are inclu
