FCC Twitch.tv Json API

Hello Campers, I’ve posted a few projects on here and I’m happy to keep posting for more feedback. I’m currently working on the Twitch tv Api and I need some feedback on the project so far. Please there should be no holding back. I also know I have a few bugs.
I can’t seem to access the streams that are offline for some reason I’d like to know why the data for some users ain’t showing up, Is it because I’m using the API proxy provided by FCC rather than the original from Twitch? I’ve been searching for the Api URL which works best on my app.
