Hourly usage data for all products is now available in the [Get hourly usage by product family API](https://docs.datadoghq.com/api/latest/usage-metering.md#get-hourly-usage-by-product-family). Refer to [Migrating from the V1 Hourly Usage APIs to V2](https://docs.datadoghq.com/account_management/guide/hourly-usage-migration.md) for the associated migration guide. This endpoint requires the `usage_read` permission. OAuth apps require the `usage_read` authorization [scope](https://docs.datadoghq.com/api/latest/scopes.md#usage-metering) to access this endpoint. ### Arguments #### Query Strings | Name | Type |
