HTTP Cat
http.cat serves a themed cat photo for most standard HTTP status codes (e.g. GET /200, /404, /451) as a static JPEG, designed for embedding directly via an <img> tag in error pages, docs, or chat-bot integrations. The current v3.x site is a static Next.js build with no server-side application logic — image responses are served straight off an Nginx config — so there's no API key, authentication, or rate limit of any kind. It's community-maintained on GitHub, where contributors submit new status-code images via a template rather than code changes.
