Cat Facts

Verified Jul 2026

catfact.ninja is a free, keyless REST API built on Laravel that serves a curated database of cat trivia facts alongside a separate cat-breed dataset (coat, pattern, country of origin, and more). Its /fact endpoint returns one random fact, while /facts and /breeds paginate through the full ~166- and 98-page collections respectively. The API documents itself via a Swagger UI hosted at its own root and throttles unauthenticated requests to 100 per minute per IP.

Cat Facts vs Dog Facts

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that original endpoint is now broken — it responds but always returns an empty fact list — and has been superseded by a rebuilt V2 API at dogapi.dog, which is what backs this entry now.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.

Cat Facts vs Dogs

The Dog CEO API serves random and breed-filtered dog images sourced from the Stanford Dogs Dataset plus community submissions, returning a direct image URL as JSON rather than the binary file itself. A live call to its breed list returns 108 main breeds and 99 named sub-breeds (42 of the mains have sub-breeds), giving 207 callable breed image paths across 165 leaf-level breed collections, each queryable via dedicated endpoints (e.g. /breed/hound/images/random), and it needs no signup or API key. The project is open-source with no pricing tier of any kind; hosting is covered by on-site ads plus voluntary PayPal donations.

Cat Facts vs MeowFacts

meowfacts is a free, keyless REST API that returns one or more random cat facts as JSON, with count and id query parameters for multiple or specific facts. A lang parameter serves community-translated fact sets in around 15 languages (English, Spanish, French, German, Korean, Russian, and others, by browser-style ISO 639 code). It's an open-source (GPL) side project hosted on a free Heroku dyno and documented via SwaggerHub, with no signup, key, or pricing tier.

Cat Facts vs RandomDog

RandomDog's woof.json endpoint returns a JSON object with a file size and a direct URL to a random dog photo, GIF, or video clip from a donation-funded, community-submitted collection. A filter or include query parameter can exclude or restrict results to specific file extensions, such as skipping mp4 clips.
