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.

BillingViewArn

The Amazon Resource Name (ARN) that uniquely identifies a specific billing view. The ARN is used to specify which particular billing view you want to interact with or retrieve information from when making API calls related to AWS Billing and Cost Management features. The BillingViewArn can be retrieved by calling the ListBillingViews API.

Type: String

Length Constraints: Minimum length of 20. Maximum length of 2048.

Pattern: ^arn:aws[a-z-]*:(billing)::[0-9]{12}:billingview/[-a-zA-Z0-9/:_+=.-@]{1,43}$

Required: No

Filter

The filters that you want to use to filter your forecast. The GetCostForecast API supports filtering by the following dimensions:

AZ
INSTANCE_TYPE
LINKED_ACCOUNT
LINKED_ACCOUNT_NAME
OPERATION
PURCHASE_TYPE
REGION
SERVICE
USAGE_TYPE
USAGE_TYPE_GROUP
RECORD_TYPE
OPERATING_SYSTEM
TENANCY
SCOPE
PLATFORM
SUBSCRIPTION_ID
LEGAL_ENTITY_NAME
DEPLOYMENT_OPTION
DATABASE_ENGINE
INSTANCE_TYPE_FAMILY
BILLING_ENTITY
RESERVATION_ID
SAVINGS_PLAN_ARN

Type: Expression object

Required: No

Granularity

How granular you want the forecast to be. You can get 3 months of DAILY forecasts or 12 months of MONTHLY forecasts.

The GetCostForecast operation supports only DAILY and MONTHLY granularities.

Type: String

Valid Values: DAILY | MONTHLY | HOURLY

Required: Yes

Metric

Which metric Cost Explorer uses to create your forecast. For more information about blended and unblended rates, see Why does the "blended" annotation appear on some line items in my bill?.

Valid values for a GetCostForecast call are the following:

AMORTIZED_COST
BLENDED_COST
NET_AMORTIZED_COST
NET_UNBLENDED_COST
UNBLENDED_COST

Type: String

Required: Yes

PredictionIntervalLevel

Cost Explorer always returns the mean forecast as a single point. You can request a prediction interval around the mean by specifying a confidence level. The higher the confidence level, the more confident Cost Explorer is about the actual value falling in the prediction interval. Higher confidence levels result in wider prediction intervals.

Type: Integer

Valid Range: Minimum value of 51. Maximum value of 99.

Required: No

TimePeriod

The period of time that you want the forecast to cover. The start date must be equal to or no later than the current date to avoid a validation error.

Type: DateInterval object

Required: Yes
