Hey there Paluri Krishnaji (MINDTREE LIMITED)
Thats a good question and thanks for using QandA platform
The rate limits are based on a sliding time window, when you make too many requests within that timeframe, you’ll be unable to make new request’s until that usage has slit it’s way out of the time window.
Have a look at these docs

If this helps kindly accept the answer thanks much.
