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 |
verify_audit_chain | Return an envelope's append-only audit-event hash chain together with a server-computed integrity verdict: every event_hash is recomputed from its canonical material, and the prev_event_hash linkage and per-envelope seq contiguity are checked. Evidence only, never PDF bytes. The raw events are inclu |
