Kairos Identity Verification review
A basic ID-and-selfie verification service with a free tier and API access.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Kairos Identity Verification helps businesses verify identities with document capture, OCR and MRZ reading, fraud and tampering checks, selfie-to-ID face matching, liveness detection, and age estimation from a photo. It supports passports, driver’s licenses, and national ID cards, while a web interface enables manual identity verification through uploads. Developers can submit verification requests and retrieve results through an API. The product is suited to small teams that need foundational ID and selfie checks for online verification workflows.
The published plans show a freemium structure. Identity Verification Free costs $0 per month and includes 100 free API calls. Identity Verification Pro costs $49 per month, includes 100 API calls, and has a lower price with higher volume. A 14-day free trial is available without requiring a card. This gives smaller organizations a low-commitment way to assess document and selfie verification before paying, while the Pro tier adds a paid platform option and volume-based pricing.
Kairos offers web, API, and self-hosted access, with cloud and self-hosted deployment options. Manual uploads provide a non-API path, while API-based requests support developer-led workflows. The documented support channel is docs, so teams should be comfortable with self-guided implementation. Its focus is the core verification sequence rather than a wide integration ecosystem or an expansive identity platform. Choose it for straightforward checks around documents, selfies, liveness, and age; organizations seeking broader platform coverage or more integration choices should evaluate alternatives.
