A zero-knowledge age verification API^? that platforms integrate to confirm a user is over a required age threshold without the platform ever seeing or storing identity documents. Using cryptographic anonymous credentials and trusted third-party attestation, users verify once and receive a reusable privacy-preserving token that proves age without revealing identity.

Multiple U.S. bills (KOSA, KOSMA) are advancing through Congress in 2026, creating immediate regulatory pressure on every platform hosting user-generated content. Platforms need compliant solutions now but lack the cryptographic expertise to build privacy-preserving systems in-house.
