Company register API returns 404 Not Found error

Hello,

I’m trying to use the Companies House API to fetch the company registers information, but I’m consistently getting a 404 Not Found error for any existing company I test with.

Here’s the API I’m using: GET https://api.company-information.service.gov.uk/company/{company_number}/registers

Other endpoints like /company/{company_number} or /company/{company_number}/officers work fine, so my authentication seems to be correct.

Has anyone else had this issue? Is there a specific type of account / access level you need to have to get the register?

Thanks!

More information on what registers are, where they are required to be kept, how they can then be accessed, and the implications on what data is available in different circumstances can be found e.g. by Googling (and probably by searching this forum).
