i tried to pull captions from YouTube using their API but wasn't able to based on permissions. Stumbled upon youtube-dl as an alternative, how does youtube-dl download captions?
i could be wrong but does it try to find the captions hosted by the original content provider? like youtube videos on HBO's channel goes to HBO.com and crawls and looks for them?

youtube-dl pulls captions the same way browser does.

I'm not sure that answers the question. A browser doesn't just pull captions. What is the source of the captions? Is it YouTube? Who's hosting the captions? These are the kind of questions I'm asking.

Wrong. Browser does pulls captions. If it wouldn't, you won't be able to watch them in web player. It should be obvious that youtube hosts captions.
