Is there a way to extract all the Studio fields defintion?

Hello,

We are working more and more with the API.
Our API are exposed on a GATEWAY portal in which all API are exposed. On this portal every API owner must provide sufficient documentation for people who will work with API.

As a result, we would like to be able to extract all the fields from STUDIO menu to be able to provide this information in our documentation.

Currently, we didn't find anyway to extract this information except doing screenshot. Do you have any suggestion on your side? 

Remark: I got the information that MicroFocus was working on an official swagger but waiting this any idea is welcome
