Public, unauthenticated endpoint for verifying that a PDF was signed through Blueink.

Submit the SHA-256 hash of a PDF file. Blueink checks whether the hash matches any signed PDF, combined PDF, or Certificate of Execution (COE) produced for a completed Bundle.

Authentication: none required. The endpoint is rate-limited for anonymous callers.

Use cases

  • Let recipients self-verify a document they received.
  • Build a verification widget into your own portal.
  • Audit-trail checks by third parties without API credentials.

Response codes

  • 200 — Hash matched a Blueink-produced document (status: verified).
  • 400 — Hash did not match any document (status: invalid) or the request was malformed (missing / invalid hash).
