Batch Image Moderation

Last updated: 2024-06-12 16:01:53
Feature Overview
The batch image moderation API adopts a sync or async POST request method. You can use this API to perform content moderation on multiple image files.
Note: 
You can moderate image files stored in COS.
You can moderate images at URLs of a third-party cloud storage vendor.
To moderate encrypted data, please contact us.
You can customize moderation policies based on different business scenarios as instructed in Setting Moderation Policy.
Restrictions
Supported image file size: < 32 MB. To moderate images larger than 5 MB in size, you need to use the large-image-detect parameter when calling the API.
Supported image quantity: Up to 100 images per request.
Supported image file resolution: a resolution of 256x256 or higher is recommended; otherwise, the recognition effect may be affected.
Supported image file format: PNG, JPG/JPEG, BMP, GIF, WEBP, or HEIF/HEIC.
Supported image URL transfer protocols: HTTP and HTTPS.
Calling the API requires a signature. For more information, see Request Signature.
SDK Recommendation
COS SDK provides complete capabilities of demo, automatic integration, and signature calculation. You can easily and quickly call APIs through the SDK. For more information, see SDK Overview.
