The detection gap
KYC platforms check the document. HTPBE? checks the file.
Two different checks – both matter.
KYC & identity platforms
Plaid · Persona · Alloy · Jumio
- Is this a real bank statement template?
- Does the account number match the identity?
- Is the document format consistent with the issuing bank?
Detects fake documents. Does not detect edited real documents.
HTPBE? tamper detection API
Structural PDF integrity
- Was this specific PDF file modified after it was generated?
- Do metadata timestamps match the file structure?
- Were digital signatures valid at the time of signing?
Catches edits invisible to visual review and template checks.
Use Cases
One undetected edit costs more than a year of prevention
One API, three critical document workflows.
Bank Statement Fraud Detection
Bank statement fraud detection for alt-lending: one approved loan on an edited statement becomes a default you can’t collect on. Catch edited balances and fabricated transaction histories before approving a loan application.
Learn more →Invoice Fraud Detection
Invoice fraud detection for AP teams: BEC invoice scams average $130,000 per incident. Detect bank account swaps and amount changes in vendor invoices before payment is processed.
Learn more →Certificate & Diploma Fraud Detection
Certificate fraud detection on hiring: one bad hire based on fake credentials costs $50K+ in recruiting, onboarding, and severance. Expose edited academic credentials and professional certificates submitted during hiring or onboarding.
Learn more →Scale Your Fraud Detection
Your team processes hundreds of documents. Automate the integrity check.
One edited bank statement that slips through underwriting becomes an approved loan you can’t collect on. HTPBE? is a document fraud detection API running 63 tamper detection checks per document via REST — results in seconds, no original file needed.

For AI coding agents
Integrate in one line
We publish a machine-readable skill file. Hand this command to your coding agent (Claude Code, Cursor, Codex) and it reads the endpoints, auth and verdict format, then writes the integration for you.

Teams that stopped document fraud
Compliance, finance, and risk teams use HTPBE? to catch manipulated PDFs before they become costly mistakes.
Caught an invoice where the total had been changed by less than a thousand dollars. Without this I would have approved it without a second look.
Sarah M.
AP Manager
United States
We had three applicants in the same week with bank statements that looked completely fine. Two of them were flagged as modified. You simply cannot see this by reading the document — it is in the file structure.
Lars V.
Risk Analyst, Online Lending
Netherlands
Salary slips were coming with altered figures. We identified two problematic files before the placement was finalised.
Priya K.
HR Operations Lead
India
Since we started checking documents this way, we stopped two applications early in the process that would have been very difficult to reverse later.
Julien R.
Fraud Analyst, Fintech
France
Some applicants were sending PDFs that looked authentic but had been edited in ways not visible to the eye. We now ask for checked originals when something is flagged. Already saved us from a few bad decisions.
Marta S.
Compliance Coordinator
Spain
One invoice was caught because there was a mismatch between the document dates and structure. That particular case would have cost us significantly.

FAQ
Frequently Asked Questions
Get answers to common questions about PDF authenticity checking.
What is HTPBE?, and what does it do?
HTPBE? (Has This PDF Been Edited?) detects whether a PDF was modified after it was created. Upload a file of up to 10 MB and get a verdict — Intact, Modified or Inconclusive — with the findings behind it.
What does HTPBE? stand for, and how do you pronounce it?
HTPBE? stands for “Has This PDF Been Edited?” Pronounce it letter by letter: H-T-P-B-E.
How is HTPBE? different from KYC platforms like Onfido or Persona?
KYC platforms confirm who a person is. HTPBE? checks whether a specific PDF file was modified after it was generated. An identity can be real while a supporting document has been edited, so the two checks complement each other.
What does the API response look like?
The API returns JSON with a status of intact, modified or inconclusive, plus the named HTPBE_ markers behind a modified verdict. There is no numeric score — every verdict is explained. Analyze returns an id; the result endpoint returns the full object.
How much does each document check cost?
Every check costs one credit, from the web app or the API — both use the same balance. You fund it with a monthly plan (from $15 for 30 credits), a one-time pack ($5 for 8, $15 for 25) or the 5 free credits every new account gets. Test API keys are free.
Do you offer test API keys?
Yes. Test keys (htpbe_test_...) are free, unlimited and available on every plan, even before you subscribe. They return deterministic synthetic results for predefined test URLs and never use credits. They cannot analyze real documents.
