Queries the byte hit ratios of accelerated domain names.

Operation description

  • You can call this operation up to 10 times per second per account.
  • If you do not set the StartTime or EndTime parameter, the request returns the data collected in the last hour. If you set both the StartTime and EndTime parameters, the request returns the data collected within the specified time range.
  • The network traffic destined for different domain names may be redirected to the same origin server. Therefore, the byte hit ratios may be inaccurate. The accuracy of query results is based on the actual configurations.

Time granularity

The time granularity varies with the time range specified by the StartTime and EndTime parameters. The following table describes the time period within which historical data is available and the data delay.

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.


Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

  • Operation: the value that you can use in the Action element to specify the operation on a resource.
  • Access level: the access level of each operation. The levels are read, write, and list.
  • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
    • The required resource types are displayed in bold characters.
    • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
  • Condition Key: the condition key that is defined by the cloud service.
  • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request parameters


The accelerated domain name. You can specify up to 100 domain names in each call. Separate multiple domain names with commas (,).

The beginning of the time range to query.

Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC.


The end of the time range to query.

Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC.

Note The end time must be later than the start time.

Response parameters


The ID of the request.

Dataobject []

The data returned.
