Liveness SDK

The VeryAI Liveness SDK opens a single-shot palm scan that confirms a live human palm is present. It's a separate SDK from the Palm Verification SDK used for palm enrollment and verification — a liveness check produces a pass/fail result only, with no user enrollment, no persistent identity, and no signed token.

What you get

• On-device palm + camera liveness check — guided camera UI, single API call
• No enrollment, no identity — just confirms a live human is present right now
• Slim or bundled model — download the recognition model on first scan, or bundle it in your app for an instant first scan
• Independent of the Palm Verification SDK — use it on its own, or alongside palm verification when a product needs both

How it works

1. Register your app in the Developer Portal and get an SDK API key
2. Configure the SDK with your sdkKey
3. Call check() — the SDK opens a guided camera flow for a single palm scan
4. The SDK creates a liveness session with VeryAI's backend, evaluates the scan, and posts the outcome
5. Your app receives a result with a success, cancelled, or error code — no signed token, no user ID
