GetCostAndUsage - AWS Cost Explorer Service


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. Management account in an organization in AWS Organizations have access to all member accounts.

For information about filter limitations, see Quotas and restrictions in the Billing and Cost Management User Guide.

Request Syntax

{ "Filter": { "And": [ "Expression" ], "CostCategories": { "Key": "string", "MatchOptions": [ "string" ], "Values": [ "string" ] }, "Dimensions": { "Key": "string", "MatchOptions": [ "string" ], "Values": [ "string" ] }, "Not": "Expression", "Or": [ "Expression" ], "Tags": { "Key": "string", "MatchOptions": [ "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, or HOURLY. If Granularity isn't set, the response object doesn't include the Granularity, either MONTHLY or DAILY, or HOURLY.

Type: String


Required: No


You can group AWS costs using up to two different groups, either dimensions, tag keys, cost categories, or any two group by types.

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 Amazon EC2, the results aren't meaningful because Amazon 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

Length Constraints: Minimum length of 0. Maximum length of 1024.

Pattern: [\S\s]*

Required: Yes


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

Length Constraints: Minimum length of 0. Maximum length of 8192.

Pattern: [\S\s]*

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

{ "DimensionValueAttributes": [ { "Attributes": { "string" : "string" }, "Value": "string" } ], "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 attributes that apply to a specific dimension value. For example, if the value is a linked account, the attribute is that account name.

Type: Array of DimensionValuesWithAttributes objects


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

Length Constraints: Minimum length of 0. Maximum length of 8192.

Pattern: [\S\s]*


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

Type: Array of ResultByTime objects
