Native SDK

The VeryAI Native SDK adds palm biometric enrollment and verification to your iOS and Android app. Users scan their palm using the device camera, and the SDK returns a signed proof of identity to your app.

What you get

• On-device palm capture — guided camera UI, no WebViews or browser redirects
• Enrollment + verification — register new users and verify returning users
• Signed identity proof — Ed25519-signed JWT token your backend can verify
• Fraud screening — AI-powered quality review flags tampered or fake palms

How it works

1. Register your app in the Developer Portal and get an SDK API key
2. Configure the SDK with your sdkKey and optional userId
3. Call authenticate() — the SDK opens the camera, guides the user through email verification and palm scan
4. On success, the SDK returns a VeryResult with an authorization code
5. Your backend exchanges the code for an id_token (JWT) via the OAuth2 token endpoint
6. Decode the id_token to get the verified user identity (sub, email)
