How pricing works
One API request per PDF. No seats, no setup fees.
Every plan is a monthly check quota. One PDF analyzed equals one request, 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 stays free for unlimited manual checks — you only pay when you automate.
