If you are intention is to hit the Twitch API, you can use My JSON Parser to easily make requests and retrieve data out of the response.

I also have a few scripts to make dealing with twitch a bit easier called mTwitch(they depend on the json parser above). With mTwitch.Core.mrc and mTwitch.StateToTopic.mrc there are custom events raised through signal to indicate things like stream online/offline:

Code:
on *:SIGNAL:mTwitch.StreamOnline:{
  echo -a $1 is online
}

on *:SIGNAL:mTwitch.StreamOffline:{
  echo -a $1 is offline
}
