Is LUIS limited for use?

I have been receiving exception in my application saying 

Exception: Response status code does not indicate success: 403 (Quota Exceeded).

Does this means we are only allowed 1000 hits per application per month on the LUIS?

Anyother justification are welcomed around this exceptions.

Solution

  • There are several quotas on LUIS's keys usage:

    • Free key:

    • 5 calls / second

    • 10 000 calls / month

    • Standard key:

    • 50 calls / second

    See Azure portal's capture below where the 5/second is visible for free plan:
