403 API error even with paid account

The site is white listed by python everywhere and the APIs are public, same script works on my local machine, but gives 403 error when making the API call on Python Everywhere

It may be that the site you are accessing is returning a 403 error -- that status code just means "access denied". If you look at the contents of the response that you are getting, it should explain why the server is denying you access.
