they most likely directly alter the DB from within python - there is no official API to do this

Was this a reply to my post? They are not amending the DB, they are simply creating the steam files and NFOs for the streaming content, and then you add that file location to Kodi to scan for library updates. It gets added to the Kodi library like regular local files. Then when you choose to play something it uses the steam rather than a local file.
