Which API should be used to get the details for this https://data.companieshouse.gov.uk

There is a publicly available link which provides details about the company by typing the URL
data.companieshouse.gov.uk/doc/company/NF004188.json without keying in API Key Details.

May I know is there any limitation in terms of usage of this link and if any is there any specific API which can overcome this?
