Limit for Text Analytics Microsoft Azure

Question

I'm using Azure Text Analytics for Sentiment Analysis. I was wondering if the API is limited to 100 requests per minute or if there is any request limit for the service.

When I tried to request more than 100 times within a minute, the API returns an empty document.

The rate limit is 100 calls per minute. Note that you can submit a large quantity of documents in a single call (up to 1000 documents). Check the Data Limits item https://learn.microsoft.com/en-us/azure/cognitive-services/Text-Analytics/overview — Hackerman, Oct 02 '17 at 20:46

As mentioned at https://learn.microsoft.com/en-us/azure/cognitive-services/Text-Analytics/overview:

Limits

Maximum size of a single document: 5,000 characters as measured by String.Length.

Maximum size of entire request: 1 MB

Maximum number of documents in a request: 1,000 documents

The rate limit is 100 calls per minute. Note that you can submit a large quantity of documents in a single call (up to 1000 documents).

It seems that the request payload size is now limited to 524288 characters. This is not reflected in the docs. – sakura-bloom Sep 10 '18 at 17:54
