@Hector Guerra for the Azure Consumption Usage Detail API https://learn.microsoft.com/en-us/rest/api/consumption/usage-details/list?tabs=HTTP, the limits are as below:
Subscription Scope: 10 Calls/min (At Tenant and Billing Account level)
All Non-subscription scope: 6 calls/min (Billing Profile and Customer scope)
Management Group scope: 2 calls/min
Billing Account scope: 6 calls/min
Enrollment Account Scope: 2 calls/min
Department scope: 2 calls/min
These limits might change and also the Consumption Usage Detail API is deprecated, and customers are advised to move to the asynchronous options available in this doc https://learn.microsoft.com/en-us/azure/cost-management-billing/automate/migrate-consumption-usage-details-api.
