Byte identity, revision ancestry, or a structural diff. Redaction check Did the black box actually remove anything, or is the text still readable underneath?

Authenticated as this account — the same call as POST /api/v1/inspect with your key.

The slug of a baseline from the panel below. On the API this is the multipart issuer field or the X-Tamperlens-Issuer header; leave it empty and the call behaves exactly as it always has.

No PDF handy? Try a sample (doesn't use quota):

Issuer baselines

Train a baseline from documents you know are genuine and Tamperlens can tell when a file does not look like it came from that issuer at all — the case a clean forgery passes every other check. Only the structural fingerprint is stored — producer, PDF version, fonts, page size — and the documents you train from are read in memory and never written to disk.

Five or more documents make a profile that can compare.
