Can we access Companies House API from US IP Addresses

Hi,

We are trying to access Companies House API from USA using Postman setup.
We registered our IP Addresses with the website and when we send request via Postman we are getting a “403 Forbidden” Message.

We also tried to explore API from Companies House website, and received below message.

Failure while contacting API. Some possible causes are connection problems or cross-origin resource sharing protection. Please check javascript domains registered against APIKey / OAuth2 registration.

It would greatly help if some one can she light on this, if it is possible to access or not, if so what changes we have to do to make it work.

Thank you in Advance.
