Connect 4chan to any app

4chan is an image-based bulletin board organised into topic boards, and it publishes a read-only JSON interface over its public content. Callers can list the available boards and their settings, fetch a board page or the full catalog of threads, retrieve a single thread with all of its posts, read the archived thread list, and get the index of threads sorted by last activity. Post records include the poster name, subject, comment HTML, timestamp, reply and image counts, and attached file names and dimensions. No credentials required.
