MeowFacts

Verified Jul 2026

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.

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that original endpoint is now broken — it responds but always returns an empty fact list — and has been superseded by a rebuilt V2 API at dogapi.dog, which is what backs this entry now.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

MeowFacts 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.

MeowFacts 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.

MeowFacts vs Cat Facts

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.
