1. API Description

Domain name for API request:

This API is used to query the user list and call quality data of a specified time range in the last 14 days. When DataType is not null, data of up to 6 users during a period of up to 1 hour can be queried each time, and the period can start on one day and end on the next. When DataType and UserIds are null, 6 users are queried by default, and data of up to 100 users can be displayed on each page (PageSize set to 100 or lower). This API is used to query call quality and is not recommended for billing.
Note: you are not advised to use the API for the processing of real-time business logic.

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