What CH data is available on the API?

Where can I find details of the data items that can be retrieved using the Companies House API. Specifically, I would like to know whether CH records contact details (email addresses) of individual members and trustees of Multi Academy Trusts and, if so, under what circumstances they can be shared.

The documentation from the API is here: https://developer.companieshouse.gov.uk/api/docs/ it includes a fairly detailed breakdown of the data returned for each call.

However they don’t record any email addresses for individuals or companies.

In general the information available for any company is identical to what you’ll find if you use the beta search site: https://beta.companieshouse.gov.uk/ (although some of that information may be derived from multiple fields or presented a little differently in the API proper)
