Var twitch API is null my 2nd API link works but not my first

I am doing the Twitch API Project and I manage to get the channel API to work but the first API that I have link only leads to null. I tried https://wind-bow.gomix.me/twitch-api that free Code Camp give but it comes up not found. Any help would be appreciated.
