Access denied | api.upstox.com used Cloudflare to restrict access

As i am trying to fetch historical data via algo, Now it is showing Access denied | api.upstox.com used Cloudflare to restrict access. Can you please check and help here.

@AshutoshSingh Could you help me understand how you’re making requests to this API and the rate at which they are being sent?

This issue occurs when Cloudflare identifies your request as originating from a bot and blocks it.
