Batch Image Moderation

Last updated: 2024-02-19 14:59:07

    Feature Description

    The batch image moderation API can adopt either sync or async POST request method. You can use this API to perform content moderation on multiple image files.
    Note:
    Moderate image files stored in COS.
    Moderate images at URLs of a third-party cloud storage vendor.
    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 above 256x256 is recommended; otherwise, the recognition effect may be affected.
    Supported image formats: PNG, JPG, JPEG, BMP, GIF, WEBP.
    Supported image URL transfer protocols: HTTP, 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.
