Amazon Elastic Compute Cloud
API Reference (API Version 2016-11-15)


Describes Reserved Instance offerings that are available for purchase. With Reserved Instances, you purchase the right to launch instances for a period of time. During that time period, you do not receive insufficient capacity errors, and you pay a lower usage rate than the rate charged for On-Demand instances for the actual time used.

If you have listed your own Reserved Instances for sale in the Reserved Instance Marketplace, they will be excluded from these results. This is to ensure that you do not purchase your own Reserved Instances.

For more information, see Reserved Instance Marketplace in the Amazon Elastic Compute Cloud User Guide.

Request Parameters

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.


The Availability Zone in which the Reserved Instance can be used.

Type: String

Required: No


Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

Type: Boolean

Required: No


One or more filters.

  • availability-zone - The Availability Zone where the Reserved Instance can be used.

  • duration - The duration of the Reserved Instance (for example, one year or three years), in seconds (31536000 | 94608000).

  • fixed-price - The purchase price of the Reserved Instance (for example, 9800.0).

  • instance-type - The instance type that is covered by the reservation.

  • marketplace - Set to true to show only Reserved Instance Marketplace offerings. When this filter is not used, which is the default behavior, all offerings from both AWS and the Reserved Instance Marketplace are listed.

  • product-description - The Reserved Instance product platform description. Instances that include (Amazon VPC) in the product platform description will only be displayed to EC2-Classic account holders and are for use with Amazon VPC. (Linux/UNIX | Linux/UNIX (Amazon VPC) | SUSE Linux | SUSE Linux (Amazon VPC) | Red Hat Enterprise Linux | Red Hat Enterprise Linux (Amazon VPC) | Windows | Windows (Amazon VPC) | Windows with SQL Server Standard | Windows with SQL Server Standard (Amazon VPC) | Windows with SQL Server Web | Windows with SQL Server Web (Amazon VPC) | Windows with SQL Server Enterprise | Windows with SQL Server Enterprise (Amazon VPC))

  • reserved-instances-offering-id - The Reserved Instances offering ID.

  • scope - The scope of the Reserved Instance (Availability Zone or Region).

  • usage-price - The usage price of the Reserved Instance, per hour (for example, 0.84).

Required: No


Include Reserved Instance Marketplace offerings in the response.

Type: Boolean

Required: No

Example Using Tokens to Manage Results

You can use pagination support to query the results sequentially and in parts.

Specify the maximum number of results that are returned in the response. Then, each paginated response contains a token that can be provided as input to a subsequent DescribeReservedInstancesOfferings call to fetch the next page. (Make sure that you use URL encoding for the token value.)
