Charity Navigator's API


Charity Navigator, America’s largest independent charity evaluator, is your source for reliable charity data. Our API provides developers access to our high-quality, comprehensive charity data which can be easily integrated into your application or website. 

  • We have detailed information on more than 8,000 of the largest charities in America. This group of public charities receives approximately half of all private contributions made in the USA each year (not including houses of worship).
  • We have basic information on the remainder of the 1.4 million US nonprofits. 

Feature Charity Navigator’s data on your site

At Charity Navigator we believe that people are amazingly generous and derive great satisfaction from helping others, but are not always sure how to help. So we built an objective rating system that assists givers from every state, and with every type of charitable interest, in finding a charity to support. Our API provides the largest dataset (more than 7,000 charities) on the Financial Health and Accountability & Transparency of US registered public charities providing services in every cause area both domestically and internationally as well as basic data on the remainder of the 1.4 million US nonprofits.

The Charity Navigator API allows you to add valuable and trusted information to your application. Via the API you can:

  • Search by keyword(s) and other criteria
  • Browse by cause areas*
  • Browse by countries served*
  • Browse Top Ten Lists and Hot Topics*
  • Display detailed ratings and metrics for individual charities*
  • Automatically access the hundreds of new ratings we publish each month
  • Automatically access additional ratings 

*Applies to rated organizations only.
