How pricing works

One check per PDF. No seats, no setup fees.

Every plan is a monthly check quota — one pool that covers both web uploads and API calls. One PDF analyzed equals one check, regardless of file size up to 10 MB or how many forensic layers fire on it. There are no per-seat charges, no setup fees, no minimum commitment.

Pick the plan that matches your monthly document volume. Upgrade the moment you outgrow it; downgrade or cancel from the dashboard at the end of the billing period. Test API keys are included on every tier so you can integrate before you scale.

The web tool at htpbe.tech gives you 5 free checks on signup — then top up per check or subscribe when you automate.

Billing FAQ

Pricing FAQ

Common questions about plans, billing, taxes, and what counts as a check.

What counts as one check?

One check equals one PDF analyzed. A single web upload or a single call to POST /v1/analyze consumes one check from your monthly quota, regardless of file size (up to 10 MB) or how many detection layers run. Web and API draw from the same pool.

Do unused checks roll over?

Your monthly subscription quota resets at the start of each billing period — unused subscription checks do not carry over to the next month. Credits you buy separately work differently: pay-per-check packs and your 5 welcome checks never expire while your account stays active. They sit in reserve and are only forfeited after 12 consecutive months with no login, upload, or API call.

Can I change or cancel my plan?

Yes. You can upgrade, downgrade, or cancel at any time from your account dashboard. Upgrades take effect immediately. Downgrades and cancellations take effect at the end of the current billing period. There is no minimum commitment.

Is there a free trial?

There is no time-limited trial. New accounts get 5 free checks on signup, usable on the web tool or the API. Test API keys are available on all plans (including before you subscribe) and return deterministic synthetic results for integration testing. You only pay when you run checks against real documents beyond your free credits.

Which plan works for a lending or fintech workflow?

Growth at $149/mo (350 checks) is the right entry point for a lender processing 200–400 loan applications per month — one check per bank statement or income document. Pro at $499/mo (1,500 checks) fits teams running multiple document checks per application or processing 1,000+ applications monthly. The Starter plan is designed for integration testing, not production volume.

Do prices include VAT?

No. All prices are exclusive of VAT. The final amount is calculated at checkout based on your location and tax status. EU businesses with a valid VAT ID pay the listed price under the reverse-charge mechanism — no VAT is added. Customers outside the EU pay the listed price with no EU VAT applied. EU consumers and customers in Finland have Finnish VAT (25.5% as of 2026) added at checkout. Tax invoices are available in your billing portal.

What does a detection result look like?

Each result returns one of three verdicts: INTACT (no signs of modification detected), MODIFIED (structural markers indicate the document was altered after creation), or INCONCLUSIVE (authenticity cannot be confirmed from structure alone). Results also include named detection markers — specific findings that explain the verdict, such as metadata date mismatches, modifications after a digital signature, or font inconsistencies across pages.
