All they did was republish their old developer API, here you can find an old copy, version 1.1.0: https://www.power-home.com/uploads/smarty/2017-02-13_123201_...

Now there used to be a way to play music (notifications, if I remember correctly) directly to the speaker, but that required an App_Key. Bose stopped handing out App_key's quite a while ago when they shutdown down their developer forums, see also: https://www.reddit.com/r/bose/comments/102ptjg/is_there_any_...
