Building secure apps with identity verification is hard. Whether it’s fintech, health tech, or access control, ensuring that users are who they claim to be, and that they’re real and present, is no small task.
But you don’t need to build the full biometric stack yourself.
That’s where the Venify Face Match & Liveness Check API comes in — a production-ready solution that combines facial recognition with real-time liveness detection, all in a single POST request.
