Get YouTube comments
List a YouTube video's top-level comments from a watch URL or video id. Per comment: id, text, author, channelId, authorAvatar, publishedTime, likeCount, replyCount, isVerified, isCreator, pinned. Sort by 'top' (default) or 'newest' and paginate with the returned nextCursor. likeCount and replyCount are YouTube's abbreviated strings (e.g. "255k", "960"), and comments come back empty when they are disabled.
Post YouTube comment
Post a top-level comment on a YouTube video. Returns the new commentId.
Get YouTube channel stats
Get a YouTube channel's stats and profile from a @handle, channel id (UC...) or channel URL. Returns channel_id, handle, name, description, subscribers, video_count, view_count, joined, country, channel_url, avatar, rss_url, is_family_safe, keywords and links. Subscribers is the abbreviated public figure (e.g. 4.51m becomes 4510000, approximate), while video_count and view_count are exact; joined is a display string (e.g. "1 Feb 2015") and each link's url is the display host without scheme.
