MeowFacts vs RandomDuck
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.
Random-d.uk's /random endpoint returns a JSON object linking to a random duck photo or GIF, with a type query parameter to request JPG or GIF specifically. A companion /randomimg endpoint serves the image file directly instead of the JSON wrapper, and the service also accepts community-submitted duck photos.
