stamp_hash | Returns a signed receipt {sha256, stamped_at, key_id, signature, public_key_url}: a booklint-family service saw this hash at stamped_at, signed with key key_id. Send ONLY a SHA-256 hex digest (64 characters). We never see or store the document — only the hash you send. This is not legal proof, notary service, evidence, or a certificate of anything. Not advice. |
verify_receiptread-only | Checks a receipt from stamp_hash against the published public keys (same check as POST /v1/verify; pass the receipt fields as arguments). Returns valid true or false with a reason. valid true means only that this service signed that hash and time with that key. This is not legal proof, notary service, evidence, or a certificate of anything. |
