4chan API
Live read-only access to the 4chan imageboard, served straight from its official JSON API — one of the most influential anonymous forums on the internet and a primary source of internet culture, exposed as clean JSON with the HTML stripped to plain text. The boards endpoint lists every one of 4chan's ~77 boards with its code, title, worksafe flag, pages, threads-per-page and a description, from /g/ (Technology) and /v/ (Video Games) to /news/, /sci/ and /pol/. The catalog endpoint returns every live thread on a board summarized — the opening post's subject and a plain-text teaser of its comment, the reply and image counts, the sticky and closed flags and when it was last bumped — sorted by activity, replies or images: the front page of the board as data. The hot endpoint self-discovers and returns the single most active thread on a board right now, fully expanded with the original post and its top replies, so you never need a thread id that has expired. The thread endpoint returns one specific thread in full by its id — the original post and every reply with author name, timestamp, plain-text comment and image filename — and falls back to the current top thread when no id is given. Everything is the live board state, nothing stored. This is the imageboard layer for any social-listening, trend-tracking, meme-research, moderation or bot app. Live from 4chan's JSON API. Distinct from Reddit, Hacker News and Lemmy APIs — this is 4chan's boards, catalogs and threads. Some boards are NSFW (worksafe flag provided). 5 endpoints, no key on our side, nothing cached.
