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.
