PDF Verification Use Cases

One API, three critical verification workflows. Integrate forensic PDF analysis into your accounts payable, HR screening, or contract management process.

Invoice Verification

Detect tampered invoices before payment. Catch altered amounts, payee details, and bank account numbers that look identical to the originals.

Multiple xref tables — primary sign of post-save editing
Incremental update chain indicating content was appended
Producer field showing an online PDF editor instead of accounting software
See integration guide

Certificate Verification

Detect fake diplomas, forged credentials, and altered certificates of completion before hiring. No original document or database required.

Consumer PDF tool as producer on an “institutional” certificate
Modification date months or years after creation date
Incremental updates on a document that should be immutable
See integration guide

Contract Verification

Detect clause changes, signature bypass, and post-signing modifications. The only verdict that reaches “certain” confidence is post-signature modification.

Modifications after digital signature — “certain” confidence verdict
Signature removal detected in document structure
Execution date inconsistency with ModDate metadata
See integration guide

Bank Statement Verification

Detect Excel-edited and fabricated bank statements before they reach underwriters. 59% of fraudulent documents in lending are bank statements.

Microsoft Excel or LibreOffice Calc as producer — not a banking system
Multiple xref tables indicating post-export editing
Modification date hours or days after creation date
See integration guide

Insurance Claims Verification

Detect altered repair estimates, inflated medical reports, and fabricated receipts at document intake, before adjuster review.

Consumer PDF editor as producer on a claims document
Incremental updates indicating post-issuance editing
Modification date after the stated incident or treatment date
See integration guide

Same API, different workflows

Every use case uses the same POST /v1/analyze endpoint. The verdict — intact, modified, or inconclusive — is the same structure regardless of document type. Only the markers in the response differ.

One integration

One API key, one endpoint. Use it for invoices, certificates, and contracts from the same account and quota.

No original needed

HTPBE analyzes the PDF’s internal structure. There is no comparison against a “clean” original or a third-party database.
