What are the REST API calls per hour limitations?

Question

When extracting metric values from Azure Monitor using the Metrics API, the limitation used to be 12000 API calls per hour. With the release this year of the Azure Monitor Metrics Data Plane API, this limit was increased to 360000 API calls per hour.

Does this new limit applies to Metrics API too?

Or does it only apply to Metrics Batch API?

@GarretaJosep-7075 Greetings from Microsoft!

The new limit of 360,000 API calls per hour applies specifically to the Azure Monitor Metrics Data Plane API, also known as the Metrics Batch API. The traditional Metrics API still adheres to the previous limit of 12,000 API calls per hour. If you need to handle a higher volume of requests, you should consider using the Metrics Batch API, which is designed to support batch operations and can handle a significantly larger number of API calls.

Hope this helps. If you have any more questions or need further assistance, feel free to ask!
