I am new to using the YouTube API. I am trying to get the Channel Category of each channel, but I don't know how to make a request to get the category.

I will give an example: http://socialblade.com/youtube/user/pewdiepie

As you can see on the Socialblade statistic of pewdiepie there is a "CHANNEL TYPE" above and the channel type or category of pewdiepie is "Games" but how did Socialblade request for that?

I hope you can help me. Thank you.
