Dogs vs RandomDog

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.

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.
