Moving from justin.tv API to new API

What is the equivalent of http://api.twitch.tv/api/stream/list.json?channel=stream1,stream2,stream3 in the new API?

I have a list of streams I need to check if they are online to display on my website (it’s 200+ streamers), and sending a request for every single one through the new https://api.twitch.tv/kraken/streams/stream1 seems incredibly wasteful.

https://api.twitch.tv/kraken/streams?channel=stream1,stream2,stream3

Thanks!
