Application Programming Interfaces
Biometric Intelligence, One HTTP Call Away.
id3's REST APIs bring face recognition, liveness detection, and document sealing to any web application — regardless of language or stack. Deploy in the cloud or on-premise, and go from integration to production in hours, not weeks.
Available APIs
Three production-ready REST APIs covering face biometrics, presentation attack detection, and cryptographic document sealing.
Face API
REST API for Web Face Recognition
REST-based web service for facial detection, recognition, analysis, and ICAO portrait quality compliance. Engineered for real-time applications with rapid response times and multi-request concurrency.
- Face detection & comparison
- 1:N identification
- ICAO portrait quality
- Presentation attack detection
BioSeal API
Cryptographic Document Sealing
Generate, decode, and verify BioSeals and Visible Digital Seals with biometric recognition capabilities. ISO 22376 compliant — any smartphone can verify offline, with no server call required.
- PKI-signed QR / DataMatrix / Aztec
- Biometric payload embedding
- Offline-verifiable seals
- ISO 22376 / 22385 compliant
Face PAD
Web-Based Liveness Detection
Web component for liveness detection with passive/active challenge-response authentication. Works in-browser across Android, iOS, and desktop — no app install required.
- Passive & active liveness
- Sub-3-second decisions
- Photo, video & 3D mask detection
- 20+ language UI support
Integration Benefits
A RESTful interface means any team — regardless of language, framework, or infrastructure — can add enterprise-grade biometrics in a single sprint.
Language Agnostic
HTTP + JSON — call from Python, Java, C#, Swift, Dart, Go, or any language with an HTTP client. No SDK installation required on the calling side.
Enterprise Security
State-of-the-art biometric algorithms validated by NIST FRTE. All endpoints secured with API key authentication and optional mTLS for on-premise deployments.
Real-Time Performance
Sub-100 ms face comparison, sub-3-second liveness decision, sub-200 ms BioSeal generation. Designed for high-throughput concurrent workloads.
Cloud or On-Premise
Deploy as a managed cloud service or run the API server within your own data center — same interface, same performance, no biometric data leaves your perimeter.
Frictionless UX
Fast, non-intrusive biometric verification. The Face PAD component handles user guidance, multilingual instructions, and session recording — no custom UI required.
Reduce Time to Market
Pre-built endpoints, ready-made code samples, and comprehensive documentation cut integration to a single sprint — no biometric expertise required on your team.
Platform Support
All APIs run server-side and are callable from any platform. The Face PAD web component is tested on all major browsers and mobile operating systems.
