AWS Cost Explorer Service
Cost Management APIs


Retrieves cost and usage metrics for your account. You can specify which cost and usage-related metric, such as BlendedCosts or UsageQuantity, that you want the request to return. You can also filter and group your data by various dimensions, such as SERVICE or AZ, in a specific time range. For a complete list of valid dimensions, see the GetDimensionValues operation. Master accounts in an organization in AWS Organizations have access to all member accounts.

Request Syntax

{ "Filter": { "And": [ "Expression" ], "Dimensions": { "Key": "string", "Values": [ "string" ] }, "Not": "Expression", "Or": [ "Expression" ], "Tags": { "Key": "string", "Values": [ "string" ] } }, "Granularity": "string", "GroupBy": [ { "Key": "string", "Type": "string" } ], "Metrics": [ "string" ], "NextPageToken": "string", "TimePeriod": { "End": "string", "Start": "string" } }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.


Filters AWS costs by different dimensions. For example, you can specify SERVICE and LINKED_ACCOUNT and get the costs that are associated with that account's usage of that service. You can nest Expression objects to define any combination of dimension filters. For more information, see Expression.

Type: Expression object

Required: No


Sets the AWS cost granularity to MONTHLY or DAILY. If Granularity isn't set, the response object doesn't include the Granularity, either MONTHLY or DAILY.

Type: String

Valid Values: DAILY | MONTHLY

Required: No


You can group AWS costs using up to two different groups, either dimensions, tag keys, or both.

When you group by tag key, you get all tag values, including empty strings.


Type: Array of GroupDefinition objects

Required: No


Which metrics are returned in the query. For more information about blended and unblended rates, see Why does the "blended" annotation appear on some line items in my bill?.

Valid values are AmortizedCost, BlendedCost, NetAmortizedCost, NetUnblendedCost, NormalizedUsageAmount, UnblendedCost, and UsageQuantity.


If you return the UsageQuantity metric, the service aggregates all usage numbers without taking into account the units. For example, if you aggregate usageQuantity across all of EC2, the results aren't meaningful because EC2 compute hours and data transfer are measured in different units (for example, hours vs. GB). To get more meaningful UsageQuantity metrics, filter by UsageType or UsageTypeGroups.

Metrics is required for GetCostAndUsage requests.

Type: Array of strings

Required: No


The token to retrieve the next set of results. AWS provides the token when the response from a previous call has more results than the maximum page size.

Type: String

Required: No


Sets the start and end dates for retrieving AWS costs. The start date is inclusive, but the end date is exclusive. For example, if start is 2017-01-01 and end is 2017-05-01, then the cost and usage data is retrieved from 2017-01-01 up to and including 2017-04-30 but not including 2017-05-01.

Type: DateInterval object

Required: Yes

Response Syntax

{ "GroupDefinitions": [ { "Key": "string", "Type": "string" } ], "NextPageToken": "string", "ResultsByTime": [ { "Estimated": boolean, "Groups": [ { "Keys": [ "string" ], "Metrics": { "string" : { "Amount": "string", "Unit": "string" } } } ], "TimePeriod": { "End": "string", "Start": "string" }, "Total": { "string" : { "Amount": "string", "Unit": "string" } } } ] }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.


The groups that are specified by the Filter or GroupBy parameters in the request.

Type: Array of GroupDefinition objects


The token for the next set of retrievable results. AWS provides the token when the response from a previous call has more results than the maximum page size.

Type: String


The time period that is covered by the results in the response.

Type: Array of ResultByTime objects


For information about the errors that are common to all actions, see Common Errors.


The requested report expired. Update the date interval and try again.

HTTP Status Code: 400


The requested data is unavailable.

HTTP Status Code: 400


The pagination token is invalid. Try again without a pagination token.

HTTP Status Code: 400


You made too many calls in a short period of time. Try again later.

HTTP Status Code: 400


Your request parameters changed between pages. Try again with the old parameters or without a pagination token.

HTTP Status Code: 400


The following is a sample request and response of the GetCostAndUsage operation that allows you to retrieve your Amazon S3 costs. For more complex examples, such as multi-level groupings, see Expression.
