A zero-knowledge age verification API that platforms can integrate to confirm a user meets an age threshold without storing or transmitting personal identity documents. Using cryptographic attestation, device-level age signals, and privacy-preserving protocols, the gateway returns only a pass/fail age check—never retaining biometric data, IDs, or birthdates on its servers.

A wave of age verification legislation (KOSA, UK Online Safety Act, California AB-1043, FTC COPPA incentives, state-level OS mandates) is creating urgent compliance demand across thousands of platforms, while public backlash against ID-based verification is intensifying the need for privacy-first alternatives.
