  title: Prove Auth API
  description: 'Phone-centric identity verification and authentication API. The Prove API (v3) uses a consumer''s mobile phone number and cryptographic possession signals to power the Pre-Fill verification flow (start, validate, challenge, complete), Unified Authentication / Trust Score (unify, unify-bind, unify-status), identity discovery (discover, fetch), phone-based Auth, and a persistent Identity Manager. All endpoints are OAuth 2.0 (client-credentials) secured; obtain a Bearer access token from the /token endpoint and send it as `Authorization: Bearer <token>` on every subsequent request.'
