BigBlueButton is now starting up.  You can access the API demos here (use FireFox for WebRTC audio/video)

  http://$HOST/demo/demo1.jsp

For API calls, use the following credentials

   host: $HOST
 secret: $SECRET

To interactively create API calls, here's a link to configure APIMate

  http://mconf.github.io/api-mate/#server=http://$HOST/bigbluebutton/&sharedSecret=$SECRET
