{"slug":"best-identity-verification-api","title":"Best identity verification API","question":"What is the best KYC and identity verification API in 2026?","verdict":"As of 2026-08-23, Claude and Gemini collectively rank Persona #1 for identity verification api on ModelsAgree — unanimous among the 2 models that have answered. The models' case: Highly configurable orchestration layer plus first-party doc/selfie/database verification, so teams can compose flows, add fallbacks, and route across vendors without. The models' main caveat: Full orchestration/case-management power lives behind higher-tier pricing and configuration effort — overkill and pricey for a team that just needs. The strongest alternative is Sumsub — All-in-one KYC/AML with unusually broad global document and coverage, liveness, ongoing AML/PEP/sanctions screening, and reusable KYC — strong value.
