Inconsistent 403/401

I’m trying to setup a query to list company directors for our partners.

I’m currently testing and querying once every 5 to 10 minutes. The same line of code occasionally works, but I routinely get 401 or 403 errors. I have registered my public API address, waited days between queries to make sure I’m not rate limited.

I’ve made sure to use the simplest possible code to not miss anything wonky:

import requests
api_key = ‘xxx’ #
find_url = “{}
query = “PARTNER NAME”
response = requests.get(url, auth=(api_key, ‘’))
if response.status_code == 200:
