I\'m using Google\'s YouTube API Explorer (alternate) to look up information on an arbitrary streaming broadcast.
No matter what I put into the id field
The Errors heading of the API documentation has this interesting chart:
Error Type | Error Detail | Description
-----------+-----------------------------+------------------------------------------
insuf...ns | insufficientLivePermissions | The request is not authorized to retrieve
| | the live broadcast.
-----------+-----------------------------+------------------------------------------
insuf...ns | liveStreamingNotEnabled | The user that authorized the request is not
| | enabled to stream live video on YouTube.
| ^ | The user can find more information at
| (I'm getting this one) | https://www.youtube.com/features.
which implies that because my account is not enabled for live streaming, I can't look at anyone else's live stream information in the API, even if I can pull it up in the browser.
This seems kind of arbitrary, but it turned out to be the permissions problem.
Note that I still can't get useful data.
