Verify a signed document.
Hash in, answer out.

Every completed DENSIGN document is hashed with SHA-256 over the final rendered file, and that hash is printed on the certificate page. Paste it here and the platform tells you whether a completed document with exactly that content exists.

Because lookup is by content hash and nothing else, document IDs cannot be enumerated and the endpoint cannot be walked to discover what has been signed.
The hash is on the certificate page of every completed document
