I can’t say for sure as I haven’t looked into it, and i’m not entirely sure what your question is, but it might be that when you load a twitch stream, you are contacting many different API servers which provide the data/stats like current views, followers, chatroom (IRC server), video stream… etc. Sorry that I can’t be more help but that is my guess!
Feel free to say that I am wrong (I probably am haha).
