：DescribeInstanceTypes

Usage notes

Take note of the following items:

• The MaxResults parameter specifies the maximum number of entries to return on each page. The maximum value of this parameter is changed from 1600 to 100. If you called this operation in 2022, you can continue to use 1600 as the maximum value of MaxResults until November 15, 2023. As of November 15, 2023, only 100 can be used as the maximum value of MaxResults. If you do not configure the NextToken parameter when you call the DescribeInstanceTypes operation, only the first page of results that contains up to 100 entries is returned. If you want to retrieve more results, configure the NextToken parameter to perform paged queries, or specify filter conditions to filter results.

• We recommend that you specify MaxResults and NextToken to perform paged queries. The first time you call the DescribeInstanceTypes operation, specify MaxResults to limit the maximum number of entries to return in the call. If the number of entries to return exceeds the specified value of MaxResults, the response includes a NextToken value. You can set NextToken to this return value and specify MaxResults in your next request to DescribeInstanceTypes to retrieve the next page of results.

• The DescribeInstanceTypes operation is used to query only the specifications and performance information of instance types. To query instance types that are available in a specified region, call the DescribeAvailableResource operation.

• To use special instance types such as instance types that are unavailable for purchase, submit a ticket.
