Free in test mode. No credit card required.

Everything you need to verify identities

From document capture to AI-powered results — a complete verification pipeline you can embed in an afternoon.

AI-Powered Verification

Document authentication, liveness detection, and face matching in a single verification flow — powered by AI that returns results in seconds.

Drop-In Iframe SDK

Embed a fully hosted verification UI with a single script tag. No React dependency, no CSS conflicts, no camera plumbing — just works.

Signed Webhooks

Receive HMAC-signed webhook events when verifications complete. Automatic retries with exponential back-off keep your system in sync.

Edge-Native Architecture

Built on Cloudflare Workers, Durable Objects, and R2. Your verification sessions run at the edge, close to your users, worldwide.

Test and Live Modes

Ship with confidence. Test mode is free and instant — flip to live mode when you're ready, with real AI checks and billing.

Flexible Billing

Monthly plans with included volume, or pay-as-you-go with USDT prepaid. No contracts, no minimums to get started.

Three steps to verified users

A REST call, two lines of JavaScript, and a webhook. That's the entire integration.

1

Create a session

Call the REST API with the customer's reference ID and your desired checks. You receive a session ID and a short-lived SDK token.

curl -X POST https://api.kyve.dev/v1/sessions \
  -H "Authorization: Bearer sk_test_..." \
  -d '{ "template_id": "tpl_abc123def456",
        "external_reference_id": "user_42" }'
2

Embed the iframe

Drop two lines of JavaScript into your page. The iframe renders the full verification UI — document upload, selfie capture, and result screens — inside your site.

<script src="https://cdn.kyve.dev/sdk.js"></script>
<script>
  Kyve.open({
    sessionId: "vs_...",
    token: "tok_...",
  });
</script>
3

Get the result

Listen for the postMessage event in the browser, or receive a signed webhook on your server. Both carry the verification outcome with check-level detail.

// Webhook payload
{
  "type": "verification_session.completed",
  "data": {
    "id": "vs_...",
    "status": "verified",
    "checks": [
      { "type": "id_document", "result": "pass" },
      { "type": "liveness",    "result": "pass" },
      { "type": "face_match",  "result": "pass" }
    ]
  }
}
