Dog Facts vs HTTP Dog

This project ("Dog API by kinduff") started in 2016 as a small Sinatra service at dog-api.kinduff.com; that original endpoint is now broken — it responds but always returns an empty fact list — and has been superseded by a rebuilt V2 API at dogapi.dog, which is what backs this entry now. The live JSON:API-formatted /api/v2/facts endpoint returns one or more random dog facts with no signup or key required. It also documents over 340 dog breeds and 20 breed groups; the maintainer funds hosting through voluntary Buy Me a Coffee donations rather than a paid tier.

http.dog serves a themed dog photo for most standard HTTP status codes (e.g. GET /200, /404, /451), following the same status-code-as-image idea as http.cat. A .json variant returns direct links to the same image in JPEG, WebP, AVIF, and JXL instead of the image itself. It's a static Cloudflare-fronted site with no server-side application logic, so there's no API key, authentication, or rate limit of any kind.
