Another similar approach, using two calls to kraken, would be to get streams from https://api.twitch.tv/kraken/streams. From these streams make calls to https://api.twitch.tv/kraken/channels/:channel/teams.
Example:
{
"streams": [
{
...
"channel": {
"name": "reynad27",
...
}
}
],
...
}
using https://api.twitch.tv/kraken/channels/reynad27/teams as the second call:
{
"teams": [
{
"_id": 2418,
"name": "cdsgaming",
"info": null,
"display_name": "CDS Gaming",
...
},
{
"_id": 1139,
"name": "tempostorm",
"info": null,
"display_name": "Tempo Storm",
...
}
]
}
