403 Error on Company Search - REST

Hi Team,

I am integrating your API to fetch company information for my application. However, I am unable to do it because of 403 error. I tried whitelisting my public IP, but I am unable to get response. Could you please help me with this?
Note: I am making call from my local machine via REST API

We’ve also been seeing intermittent 403 errors for the last 2 days
