# Verify a clinician's license, live, in one call

Four primitives

Same key, same SDK, same error model. Use one or all four.

Auth →

OAuth 2.0 and OIDC sign-in with biometric verification. Drop-in replacement for "Sign in with Google," with proof-of-personhood built in.

OAuth 2.0OIDCFederationSessions

Identity →

Verify a real human, check a professional license, prove an attribute without revealing it. KYC and credential proofs in one resource.

KYCLicense checksFace matchZK proofs

Agents →

Authorize an AI agent to act on a verified human's behalf. Broker credentials, scope access, log every action — all without the agent ever holding a long-lived secret.

Webhooks →

Real-time events for every verification, credential change, agent action, and approval. Signed payloads, automatic retries, replay-safe.

Built for the way you ship

Test mode by default

Every account starts in test mode. Synthetic identities and licenses, predictable outcomes, zero PHI risk. Flip a flag for production — same endpoints, same SDKs.

Idempotency on everything

Pass an Idempotency-Key header on any state-changing request. Retries during network blips become safe by default — no double verifications, no duplicate approvals.

SDKs in 6 languages

TypeScript, Python, Go, Ruby, PHP, Java. Generated from our OpenAPI spec, typed end-to-end, versioned with the API. Or use any HTTP client.

Build with what you already know
