Hatena Bookmark API

healthy 3,127 Subscribers

Japan's biggest social-bookmarking trends from Hatena Bookmark (b.hatena.ne.jp), read keyless. "Hatebu" is the Japanese internet's collective save button: when something is worth reading, Japanese users bookmark it, and the most-bookmarked links become the country's de-facto trending list across technology, society, business, life, learning, fun and games. The hot endpoint returns the established popular entries for a category — the links that have gathered the most bookmarks. The new endpoint returns the newly-rising entries gaining bookmarks fast right now, the leading edge before they hit the hot list. Each entry carries its title, URL, bookmark count, category and date. The count endpoint looks up the exact bookmark count for any one or more URLs — useful to gauge how much attention a page (yours or a competitor's) has drawn on the Japanese web. This is the Hatena Bookmark cut — a distinct social-bookmarking platform, separate from the developer, blogging and streaming feeds in the catalogue, and the cleanest read on Japanese-web attention. Bookmark counts are the real, live numbers Hatena shows; titles are Japanese as Hatena publishes them (HTML entities decoded). A short cache fronts the upstream. Keyless.

Qiita Developer Community API

Articles, engagement and trending tech tags from Qiita (qiita.com), Japan's largest developer knowledge-sharing community, read keyless from its public v2 API. Qiita is where Japanese engineers post how-tos, deep-dives and notes, and where the community signals quality with LGTM ("looks good to me") likes and "stocks" (saves) — the Japanese counterpart to dev.to or Medium's engineering side, with its own metrics and its own tech-topic rankings. The articles endpoint searches and lists articles, each with its title, LGTM likes, stocks (saves), comment count, tags and author — filterable by keyword, tag and a minimum-stocks threshold so you can surface the popular pieces. The article endpoint returns one article in full by its id. The tags endpoint ranks Qiita's tech tags by how many articles and followers they have — the live map of what Japanese engineers care about (Python, AWS, React and the rest). This is the Qiita platform cut — a distinct social and developer platform, separate from dev.to, Medium and the other blogging and social feeds in the catalogue, with its own LGTM/stock engagement model. Likes are LGTM up-votes and stocks are saves/bookmarks — two distinct Qiita signals; follower and article counts are the real, live community numbers. Titles and tags are in Japanese (and English) as Qiita publishes them. Qiita rate-limits unauthenticated callers, so a longer protective cache fronts the upstream and stale data is served if the limit is hit. Keyless.

pixiv Rankings & Artwork API

Live rankings and artwork engagement from pixiv (pixiv.net), Japan's dominant art-and-illustration social network, read keyless from pixiv's public ranking and artwork endpoints. pixiv is where millions of illustrators, manga artists and animators post their work and where fans drive it up the daily, weekly and monthly rankings with views and bookmarks — the platform at the centre of anime and illustration fan culture, far bigger in that world than DeviantArt or ArtStation. The ranking endpoint returns the official pixiv ranking for a mode (daily, weekly, monthly, rookie, original, and the male/female popularity cuts) — the top works ranked, each with its rank (and previous-day rank), title, artist, view count, ranking points (bookmark-weighted), work type and tags; pass a content filter (illust, manga, ugoira), a page (1-10, 50 per page) or a past date. The illust endpoint returns one artwork in full by its pixiv id: its view, bookmark, like and comment counts, tags, dimensions, page count, upload date and age-restriction flag. This is the pixiv platform cut — a distinct social and creative platform, separate from danbooru (an imageboard aggregator) and from the other social and art feeds in the catalogue. Only safe-for-work ranking modes are exposed; individual artworks carry an x_restrict flag so age-restricted works are clearly labelled, not hidden. Counts are the real, live numbers pixiv shows; a short cache fronts the upstream. Keyless.

SHOWROOM Live Streaming API

Live data from SHOWROOM (showroom-live.com), the Japanese live-streaming platform built around idols and talent, read keyless from its public web API. SHOWROOM is where AKB48, Nogizaka46 and thousands of aspiring idols, voice actors and creators broadcast and where fans send virtual gifts in real time — a streaming culture quite unlike Twitch or Kick. This exposes who is live right now, how many are watching, which genres are hot and each room's standing. The live endpoint lists the rooms broadcasting right now across every genre, ranked by viewers, each with its streamer name, current viewer count, genre and how long it has been live (the "Popularity" overlay is de-duplicated so every room is counted once under its real category). The genres endpoint aggregates the live picture by category — idols, talents, virtual streamers, music and more — with each genre's number of live rooms and total viewers, so you can see where the audience is. The room endpoint returns one room's profile by its room id: the room name, its follower count, its room level (SHOWROOM's standing metric) and whether it is live now. This is the SHOWROOM platform cut — a distinct social/streaming platform, separate from the Twitch, Kick, Bilibili, Niconico and other feeds in the catalogue. Viewer and follower counts are live; nothing is stored beyond a short cache. Counts are integers; times are UTC.

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).
