Each comment that has replies carries a repliesCursor. Send that value in comment, and the call returns the replies to that comment.
sort takes top or newest. The default is top.
Send the cursor from the last response, with the same video and sort. A request with a cursor needs an API key.
1 credit for each call that returns data. A call that returns an error or an empty list uses 0 credits.
