Common
questions.
What happens when I hit my monthly limit?
We do not bill overages. Once you reach your monthly limit the API returns a 429 with the reset date, so you can never get a surprise invoice from us. The tradeoff is real and worth planning for: verification stops until the limit resets, so handle a 429 the same way you handle us being unreachable and let the request through. You can upgrade at any time.
Can I switch plans later?
Yes. You can upgrade or downgrade at any time from your dashboard. Upgrades take effect immediately; downgrades apply at the start of the next billing cycle.
Is there a free plan?
Yes. Every account starts with 14 days of Starter, no credit card, and when those run out it drops to Free rather than stopping: 1,000 verifications a month, for ever, with the AI-agent verdict included. It is not enough to run a real signup form on, and that is deliberate. When 1,000 stops being enough, $19 for 10,000 is the next step, and $49 after that. If it never stops being enough, you did not need to pay me.
What counts as a verification?
One POST to /api/v1/verify counts as one verification, regardless of the result (human or bot). Requests rejected for a bad key or a rate limit are not counted. Session monitoring only records a verification on the heartbeat that actually flags an anomaly, so a quiet session costs you nothing.
Do you store personal data?
No. useHUMA analyzes behavioral patterns (mouse speed, typing cadence, scroll rhythm) — we never store your end users' names, emails, IP addresses, or any PII. We store the anonymized userId your system provides plus the summary signal numbers used to produce the score. See the privacy policy for exactly what that means.
What is the Enterprise plan?
Enterprise is designed for high-volume products and teams that need a dedicated Slack channel, custom terms and invoicing, and volume pricing. Support is answered by the founder within one business day. Reach out to team@humaverify.com to discuss your requirements.
Can HUMA detect AI agents (Playwright, Puppeteer, browser extensions)?
Playwright, Puppeteer and Selenium as they ship, yes. Agent Shield is included on every paid plan, and every verification returns a separate is_agent verdict alongside the human result. What it does not catch is an agent modified specifically to erase the traces automation normally leaves while driving a visible browser — that one we do not claim, and it is written up on our limits page. If you are defending against that class specifically, email team@humaverify.com and tell us what you are seeing before you buy.
