1. API Description

Domain name for API request:

This API (DescribeAutoScalingInstances) is used to query the information of instances associated with AS.

  • You can query the details of instances based on information such as instance ID and auto scaling group ID. For more information on filters, see Filter.
  • If the parameter is empty, a certain number (specified by Limit and 20 by default) of instances of the current user will be returned.

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