Official documentation for 4chan's read-only JSON API, describing endpoints for boards, threads, catalogs, and archives served from a.4cdn.org. It is a docs repository rather than executable software, including API rules, rate limits, and terms of service.
Use cases
- fetch 4chan threads as json
- build a 4chan thread watcher
- list boards and catalog data from 4chan
- scrape imageboard posts programmatically
- understand 4chan api rate limits and endpoints
When to choose
- you are building a client or reader app for 4chan content
- you need the authoritative reference for 4chan API endpoints and JSON schemas
- you want to comply with 4chan's API rules and terms of service
When to avoid
- you need a write/posting API - it is read-only
- you need a client library or SDK rather than documentation
- you want to mirror or rehost 4chan content, which the terms forbid
