• create_proof

  Stamp content with a permanent provenance record. Pass the sha256 hash of the content (hash it locally; the content itself is never uploaded). Returns an instant signed receipt: attach its verifyUrl, byline, badgeEmbed, and qrUrl to the published artifact. The receipt's `publish…

• reveal

  Retrieve escrowed content for a proof you have been granted access to. Only available for proofs created with content escrow opted in (not yet available — stamps are hash-only today). The service re-checks H(content) == stampedHash before returning.
