Face Comparison

The Face Comparison API enables automated facial matching between two images, commonly used for identity verification workflows.

Overview

This API compares a reference face image (e.g., from an ID document) against a live or uploaded photo to determine if they belong to the same individual. Unlike the ICR extraction API, face operations are synchronous — results are returned directly in the response with no polling required.

Key Features

Synchronous responses — no polling needed

1:1 face matching with confidence scoring and liveness detection

1:N face search across indexed databases

Use Cases

KYC verification — Match a selfie against an ID document photo during customer onboarding
Access control — Verify identity for secure area access or transaction authorization
Duplicate detection — Identify duplicate accounts using facial matching across submissions
Watchlist screening — Search a submitted face against an indexed database of known individuals

Authentication

Face Comparison endpoints use the same HTTP Basic Authentication as the ICR API.

Authorization: Basic <base64_encoded_client_id:client_secret>
