chucknorris.io vs JokeAPI

chucknorris.io is a free, keyless JSON API serving hand-curated Chuck Norris jokes, either fully random or filtered across 16 categories (career, dev, movie, political, sport, and more). It also supports free-text search over the joke corpus and returns each joke with a permalink and an icon-URL field for quick embedding. There's no rate limit, no signup, and no paid tier — it's run as a hobby project on Heroku behind Cloudflare.

JokeAPI (Sv443) serves programmable jokes across 7 categories — Misc, Programming, Dark, Pun, Spooky, Christmas, and a catch-all Any — with content filtering by flag (nsfw, religious, political, racist, sexist, explicit) so integrators can enforce a safe-mode. A single GET can return the response as JSON, XML, YAML, or plain text via a `format` query parameter, and jokes come as either single one-liners or two-part setup/delivery pairs. It's free, keyless, open source, and self-hosted by its maintainer with no paid tier.
