DescribeSpotPriceHistory

Describes the Spot price history. For more information, see Spot Instance Pricing History in the Amazon Elastic Compute Cloud User Guide.

When you specify a start and end time, this operation returns the prices of the instance types within the time range that you specified and the time when the price changed. The price is valid within the time period that you specified; the response merely indicates the last time that the price changed.

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.

AvailabilityZone

Filters the results by the specified Availability Zone.

Type: String

Required: No

DryRun

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

EndTime

The date and time, up to the current date, from which to stop retrieving the price history data, in UTC format (for example, YYYY-MM-DDTHH:MM:SSZ).

Type: Timestamp

Required: No

Filter.N

One or more filters.

  • availability-zone - The Availability Zone for which prices should be returned.

  • instance-type - The type of instance (for example, m3.medium).

  • product-description - The product description for the Spot price (Linux/UNIX | SUSE Linux | Windows | Linux/UNIX (Amazon VPC) | SUSE Linux (Amazon VPC) | Windows (Amazon VPC)).

  • spot-price - The Spot price. The value must match exactly (or use wildcards; greater than or less than comparison is not supported).

  • timestamp - The timestamp of the Spot price history, in UTC format (for example, YYYY-MM-DDTHH:MM:SSZ). You can use wildcards (* and ?). Greater than or less than comparison is not supported.
