Detailed, practical walk-throughs of how businesses use FinAuth's identity verification API — which checks to combine, how the flow looks to the end user, and what to watch for operationally.
FinAuth provides KYC and compliance building blocks behind one API: ID document verification, biometric verification (passive liveness + selfie-to-ID face match), age estimation, AML/PEP/sanctions screening, KYB (business lookup + UBO/ownership checks), transaction screening (KYT), crypto wallet screening, reusable sessions, hosted verification flows (link or QR), and signed webhooks. Each use case below composes a different subset.
- Fintech Onboarding — compliant KYC for neobanks, wallets, and payment apps
- Crypto Exchange KYC — onboarding plus wallet screening and transaction monitoring
- Marketplace & Platform Verification — seller trust, payout gating, and fraud reduction
- Age Verification — low-friction age gates with document fallback
- KYB: B2B Onboarding — verifying business customers and their owners
| If you are… | Start with |
|---|---|
| A regulated fintech | Fintech Onboarding |
| An exchange / VASP | Crypto Exchange KYC |
| A marketplace or gig platform | Marketplace Verification |
| Selling age-restricted goods/content | Age Verification |
| Onboarding companies, not consumers | KYB |
All flows share the same integration skeleton — create a hosted session, hand the user to it, act on the webhook — documented in the Identity Verification API Guide. The regulatory background is in the KYC Compliance Handbook.
FinAuth is self-serve with a free tier: create an account at finauth.io, generate an API key, and run your first hosted verification session the same day. Current pricing: finauth.io · API details: docs.finauth.io.
