Concurrent request failure for Timeseries API . Cant take four request per second

I am trying to use Timeseries API for 5 mins interval. While the API works fine during non market hours with one request per second.
API loaded with four request per second, causes failure.
I believe the API was to support 10 request per second.

In fact even 2 request per second on the Timeseries API fails after few minutes.

Any fix available ?

Hi Kumar_M,

Currently, we are providing a rate limit of 3 requests per second for the Timeseries API. However, we understand that this limit may not be sufficient for your needs.
In the near future, we plan to increase the rate limit to accommodate higher request volumes. This will ensure a smoother experience and reduce the chances of failures, even when making multiple requests per second.
Thank you for bringing this to our attention, and we appreciate your patience as we work towards resolving this issue
