FAQ

What does HTPBE? stand for, and how do you pronounce it?

HTPBE? stands for Has This PDF Been Edited? – it is the product name, not a random code.

How to say it

Pronounce it letter by letter: H-T-P-B-E, the way you would say ‘FBI’ or ‘API’. The letters do not spell a word, so spelling them out is the clearest option on a call, in a support chat or in a demo. In writing it is five capital letters with no punctuation, and the domain is htpbe.tech.

Why the name is a question

The name is the question the service answers. You give it a PDF and it replies with one of three verdicts:

  • Intact – no structural evidence that the file was edited after it was created.
  • Modified – evidence that it was.
  • Inconclusive – the file’s origin can’t vouch for it, for example because it came from software that anyone can use to build a document from scratch.

What the name does and does not promise

‘Edited’ refers to the file. HTPBE? tells you whether the PDF was changed after it was generated. It does not tell you whether the content is true, who sent it, or whether the issuer really produced it.

For what the service checks, see What is HTPBE?, and what does it do? For how to read each verdict, see How should I interpret PDF analysis results?

Basics & ScopePricing & API

Basics & Scope

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.

Pricing & API

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.

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 free credits. New accounts get 5 free credits on signup. Test API keys are free.
