1. API Description

Domain name for API request: iai.intl.tencentcloudapi.com.

This API is used to detect the liveness of faces in images uploaded by users and determine whether these images are photographed.

Compared with normal Image-based Liveness Detection services, this API enhances the defense capability against attacks from HD screens, printed photos, and 3D masks, as well as improves attack blocking four to five times the competing products, while maintaining high accuracy. It also supports face verification in different use cases, and satisfies the image-based liveness detection needs on mobile or PCs, making it ideal for liveness detection applications in various industries.

Pay-as-you-go billing officially started for this API at 00:00, August 1, 2022. For more information, see Billing Overview.
