Next.js Integration

Use CheckHumans as a decision layer inside your Next.js product.

Capture event context in client or server flows, send it to the v2 API, and use the response to decide how onboarding, auth, or lead routing should behave.

Example

const decision = await fetch("/api/v2/decide", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    siteKey: process.env.NEXT_PUBLIC_CHECKHUMANS_SITE_KEY,
    eventType: "signup",
    email,
    session: {
      eventsInLastHour,
      timeToSubmitMs,
      deviceConsistency
    }
  })
}).then((r) => r.json());

Run the same trust decision layer in app router forms, API routes, and login checkpoints.

Treat score responses as business inputs instead of widget verdicts.

Roll out one protected flow first, then extend to more routes, policies, and agent controls.
