    1. API Description

    Domain name for API request: vod.tencentcloudapi.com.

    This API is used to get file attributes asynchronously.

    • Currently, this API can only get the MD5 hash of a file.
    • If the file queried is in HLS or DASH format, the attributes of the index file will be returned.

    A maximum of 20 requests can be initiated per second for this API.

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

    2. Input Parameters
