meterUsage method

As a seller, your software hosted in the buyer's Amazon Web Services account uses this API action to emit metering records directly to Amazon Web Services Marketplace. You must use the following buyer Amazon Web Services account credentials to sign the API request.

• For Amazon EC2 deployments, your software must use the IAM role for Amazon EC2 to sign the API call for MeterUsage API operation.
• For Amazon EKS deployments, your software must use IAM roles for service accounts (IRSA) to sign the API call for the MeterUsage API operation. Using EKS Pod Identity, the node role, or long-term access keys is not supported.
• For Amazon ECS deployments, your software must use Amazon ECS task IAM role to sign the API call for the MeterUsage API operation. Using the node role or long-term access keys are not supported.
• For Amazon Bedrock AgentCore Runtime deployments, your software must use the AgentCore Runtime execution role to sign the API call for the MeterUsage API operation. Long-term access keys are not supported.

The handling of MeterUsage requests varies between Amazon Bedrock AgentCore Runtime and non-Amazon Bedrock AgentCore deployments.

• For non-Amazon Bedrock AgentCore Runtime deployments, you can only report usage once per hour for each dimension. For AMI-based products, this is per dimension and per EC2 instance. For container products, this is per dimension and per ECS task or EKS pod. You can't modify values after they're recorded. If you report usage before a current hour ends, you will be unable to report additional usage until the next hour begins. The Timestamp request parameter is rounded down to the hour and used to enforce this once-per-hour rule for idempotency. For requests that are identical after the Timestamp is rounded down, the API is idempotent and returns the metering record ID.
• For Amazon Bedrock AgentCore Runtime deployments, you can report usage multiple times per hour for the same dimension. You do not need to aggregate metering records by the hour. You must include an idempotency token in the ClientToken request parameter. If using an Amazon SDK or the Amazon Web Services CLI, you must use the latest version which automatically includes an idempotency token in the ClientToken request parameter so that the request is processed successfully. The Timestamp request parameter is not rounded down to the hour and is not used for duplicate validation. Requests with duplicate Timestamps are aggregated as long as the ClientToken is unique.

If you submit records more than six hours after events occur, the records won't be accepted. The timestamp in your request determines when an event is recorded.

You can optionally include multiple usage allocations, to provide customers with usage data split into buckets by tags that you define or allow the customer to define.

For Amazon Web Services Regions that support MeterUsage, see MeterUsage Region support for Amazon EC2 and MeterUsage Region support for Amazon ECS and Amazon EKS.

May throw CustomerNotEntitledException. May throw DuplicateRequestException. May throw IdempotencyConflictException. May throw InternalServiceErrorException. May throw InvalidEndpointRegionException. May throw InvalidProductCodeException. May throw InvalidTagException. May throw InvalidUsageAllocationsException. May throw InvalidUsageDimensionException. May throw ThrottlingException. May throw TimestampOutOfBoundsException.

Parameter productCode : Product code is used to uniquely identify a product in Amazon Web Services Marketplace. The product code should be the same as the one used during the publishing of a new product.

Parameter timestamp : Timestamp, in UTC, for which the usage is being reported. Your application can meter usage for up to six hours in the past. Make sure the timestamp value is not before the start of the software usage.

Parameter usageDimension : It will be one of the fcp dimension name provided during the publishing of the product.

Parameter clientToken : Specifies a unique, case-sensitive identifier that you provide to ensure the idempotency of the request. This lets you safely retry the request without accidentally performing the same operation a second time. Passing the same value to a later call to an operation requires that you also pass the same value for all other parameters. We recommend that you use a UUID type of value.

If you don't provide this value, then Amazon Web Services generates a random one for you.

If you retry the operation with the same ClientToken, but with different parameters, the retry fails with an IdempotencyConflictException error.

Parameter dryRun : Checks whether you have the permissions required for the action, but does not make the request. If you have the permissions, the request returns DryRunOperation; otherwise, it returns UnauthorizedException. Defaults to false if not specified.

Parameter usageAllocations : The set of UsageAllocations to submit.

The sum of all UsageAllocation quantities must equal the UsageQuantity of the MeterUsage request, and each UsageAllocation must have a unique set of tags (include no tags).

Parameter usageQuantity : Consumption value for the hour. Defaults to 0 if not specified.
