Petfinder v1 Legacy API

Petfinder API v2.0 is now available by requesting a key below. Petfinder’s legacy API (v1.0) will be retired in January 2020. Please transition to v2.0 as soon as possible. You can still access the Petfinder API v1.0 documentation or access your existing API account.

Petfinder for Developers

Petfinder is dedicated to helping pets find homes, and we know you are too. Petfinder's free API is another way we extend your reach to get pets adopted.
The API provides ready access to data for Petfinder's hundreds of thousands of adoptable pets and the organizations that care for them.

Shelters and Rescues

  • Upload your pets on Petfinder.com and display them anywhere, like on your organization's website.
  • Pull your Petfinder listings into your shelter software with the API instead of adding them manually.

App Developers

  • Display adoptable pets from Petfinder in your web or mobile app.
  • Help users find their perfect pets by location, breed, and other characteristics.

Start Using the API

Basic access is granted automatically after collecting a few details and will allow you to make up to 1,000 requests/day, with a rate limit of 50 requests/second. If you need more bandwidth, you can request more once you have your basic key.
