Kairos AR

Kairos AR, Inc. is a Miami-based human-analytics company providing face recognition, facial detection, and emotion analysis as a REST API. The platform lets developers enroll, verify, and recognize faces against galleries they create, detect faces and facial features (age, gender, ethnicity, glasses, landmarks) in photos, and analyze emotion, demographics and attention across images and video. Requests and responses are JSON and every call is authenticated with an app_id + app_key header pair. Kairos ships official SDKs for JavaScript, PHP, Android, and .NET, publishes an Apiary-hosted API reference with a live sandbox console, and offers a free tier plus usage-based pricing and an on-premise biometric offering. The company was surfaced as a 500 Global portfolio company and is enriched here into the API Evangelist network.

Kairos AR publishes 3 APIs on the APIs.io network: Emotion Analysis API, Face Recognition API, and Galleries API. Tagged areas include Company, Face Recognition, Facial Recognition, Biometrics, and Emotion Analysis.

Kairos AR’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 17 more developer resources.
