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.
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:
And link to LUIS pricing here
There is also (or was) an out of Azure preview key good for only 1000 messages per month on a rolling daily window. Not sure if it’s still there but it could be what you’re running into. It was called the bootstrap key and was just using your programmatic api key as the runtime key.
