Search YouTube videos
Search YouTube videos by query, or list a channel's or playlist's videos from its URL. Returns a list of videos with id, title, url, duration, channelName, channelUrl, viewCount, date, thumbnailUrl, and description.

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.
Get YouTube channel stats

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.
