Billable usage is the measured amount of your usage for a HERE billable service, as per licensing terms.
The billable usage you are charged for is dependant on what you ordered, and may include content, data, location services, pipelines, and SDKs.
The Usage API is available to monitor the billable usage costs for your organization's products, allowing you to manage them easily.
Billable usage varies by the service. As an example, Data transfer is measured in GB and the billable usage is calculated per hour. You can estimate your costs at any point in time, using the current HERE pricing to calculate your billable usage costs.
