Niconico Video API
Live video, search and engagement data from Niconico (nicovideo.jp), the pioneering Japanese video platform that invented danmaku — the comments that scroll across the video itself — read keyless from Niconico's public Snapshot Search API and video-info endpoint. Niconico is one of Japan's biggest video communities, the home of Vocaloid, "Let's Play" culture and a vast catalogue with videos counting tens of millions of views and millions of overlaid comments. This exposes what is popular, who is watching and how each video is performing across Niconico's distinctive engagement signals — views, the famous scrolling comments, mylist bookmarks and likes. The search endpoint finds videos by keyword, sorted by views, comments, mylists, likes or upload date — the way to surface the platform's most-watched and most-discussed content. The tag endpoint browses an exact Niconico tag (the platform's main discovery axis — VOCALOID, ゲーム/games, 音楽/music, アニメ/anime) ranked by views, so you can see what leads a category. The video endpoint returns one video's full detail by its watch id (the sm/nm/so id), including its description, tags, length, upload date and uploader. This is the Niconico platform cut — a distinct social/video platform, separate from the YouTube, Bilibili, TikTok, BitChute and other platform feeds in the catalogue. View, comment, mylist and like counts are live; nothing is stored beyond a short cache. Counts are integers; dates are as the platform reports them (JST).
