2 chase-manning 0 7/3/2025, 8:26:00 AM

Open Dog Registry is a public JSON API that returns detailed data for 200+ dog breeds.

• Website: https://registry.dog/ • One-call endpoint: https://registry.dog/api/v1 • Returns general info, personality traits, care stats, plus indoor/outdoor/studio images • MIT-licensed, zero auth, free for personal or commercial use • Cache-friendly: please cache where possible to keep the service fast • Built with TypeScript, hosted on Cloudflare Workers (cold start ≈15 ms)

I built it to simplify pet-finder projects and vet apps that need structured breed data. Feedback, pull requests, and GitHub stars are welcome!
