Improve documentation / provide llms.txt file

Hi, thank you for all your excellent APIs! They are great.

Unfortunately the documentation is a bit lacking. The interactive code builder is a bit buggy (the API request body doesn't change when you toggle the settings), and it's difficult to get a clear sense of the response payload body shape. Could you please provide clear documentation for the APIs, perhaps in the form of llms.txt, so that I can more easily integrate these systems?
