Welcome to the Aurigin API

The Aurigin API provides powerful audio analysis capabilities for deepfake detection and voice identification. Our REST API is designed for ease of use while providing enterprise-grade performance and reliability. Two layers of voice security:
  1. Deepfake Detection → Verify if a voice is authentic or AI-generated
  2. Voice Identification (Voice ID) → Confirm who is speaking by matching against enrolled voiceprints
Together, these capabilities create a comprehensive foundation for voice fraud prevention and identity verification.

​
Base URL

All API requests are made to: 
https://api.aurigin.ai/v1

​
Authentication

All endpoints require authentication via API key in the X-Api-Key header: 
curl https://api.aurigin.ai/v1/predict \
  -H "X-Api-Key: YOUR_API_KEY"
Get your API key from the Aurigin Dashboard
