Build on proof
REST API. Full OpenAPI spec. Sandbox environment. Live in hours.
Provium Proof is an API-first identity verification platform. Start a sandbox, grab credentials, and start verifying identities — without storing a single passport scan.
What the API gives you
REST + OpenAPI
Standard HTTP verbs, JSON responses, and a fully documented OpenAPI 3.1 specification.
Sandbox environment
Full test environment with simulated identity verification flows.
OIDC + OAuth 2.0
Standard authentication flows. Works with every language, framework, and API gateway.
Cryptographic receipts
Verification results are W3C Verifiable Credentials — signed, exportable, and verifiable.
Multi-jurisdiction checks
One API covers identity, right-to-work, age, KYB, background checks.
Webhook notifications
Real-time webhook events for verification completion — no polling required.
