''Note that these are currently described in terms of a REST (or, at least, REST-like) interface on the Loop server. There is a significant possibility that this interface will evolve to be JSON objects exchanged on a WebSockets connection, similar to the network API exposed by the Simple Push Server.''
[http://docs.services.mozilla.com/loop/index.html Current as-built documentation] of the API is available from the Mozilla Services Documentation web page.
