# Overview

OOTO API is a biometric recognition platform that provides robust tools for face template management, face identification, liveness and deepfake detection, and document OCR.

The platform is designed for integration into mobile and web applications, supporting identity verification, access control, onboarding, and anti-fraud processes.

OOTO offers a simple HTTP-based API with no SDK dependencies, working via standard HTTPS requests.

***

#### Supported Capabilities

* Face Enrollment — store facial templates from user photos
* Face Identification (1:N Search) — find the most similar face template from your database
* Face Verification (1:1) —  verify if two face images belong to the same person
* Liveness Detection — detect whether the input is from a real, live person
* Deepfake Detection — detect whether the input image has signs of AI manipulation
* Document OCR — extract structured identity data from document images
* Selfie-to-Document Matching — compare a document portrait with a selfie

***

#### Integration Flow Example

Typical usage flow:

1. Enroll — Capture user photo and send to POST /face-api/add to create a template
2. Identify — Later, submit a face image to POST /face-api/identify

   → The API returns the closest matching templateId (if any)
3. (Optional) Run liveness or deepfake checks via query parameters or separate endpoints
4. (Optional) Delete template when no longer needed
