Best Identity Verification (KYC) APIs

Identity Verification (KYC) APIs let developers confirm a user is who they claim to be, capturing a government ID, running a liveness/selfie biometric match, and optionally screening against sanctions/AML watchlists, then returning a pass/fail decision via REST API plus drop-in web and mobile SDKs. The category splits into developer-first, self-serve players (Stripe Identity, Persona, Sumsub, Veriff) that publish per-verification pricing and offer instant sandbox keys, and enterprise, sales-gated incumbents (Onfido/Entrust, Jumio, Socure, and to a degree Plaid) that win on global document coverage, fraud signals, and regulatory depth but hide pricing behind quotes. Compare on: developer experience and quickstart speed, breadth of official SDKs, reliability/scale, and how fast a developer or AI agent can self-serve a working key without a sales call.
