Bots, scripts, and now AI browser agents flood signup forms with fake accounts — inflating your metrics, burning your email reputation, and abusing free trials. useHUMA blocks them with a single API call at the moment of signup, using behavioral detection. No CAPTCHA, no friction for real users, no PII.
Junk signups skew your activation and conversion metrics, burn your email-sending reputation on bounces, abuse free trials, and quietly run up your database and infra bills. The damage is done before a human ever notices.
Scripts (Playwright, Puppeteer, Selenium) and AI browser agents now fill out signup forms like a person would. Agent Shield flags these directly, returning an is_agent score alongside the human verdict on Pro & Enterprise.
CAPTCHAs punish your real users at the worst possible moment — the signup — while modern bots solve them anyway. useHUMA verifies humans invisibly from behavioral signals, so genuine sign-ups never see a puzzle.
Drop the collector on your form and POST to /api/v1/verify on submit. Get back human and confidence in milliseconds, and reject signal-less or agent traffic before it ever hits your database. Any stack.
// On submit, send the collected signals with the new user POST https://humaverify.com/api/v1/verify Authorization: Bearer YOUR_API_KEY { "userId": "new_user_id", "sessionData": { ... } } // Reject the signup if it isn't a real human → { "human": false, "confidence": 0.04, "agent": { "is_agent": true } }
