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. 

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 and updated ratings we publish each month.*

*Applies to rated organizations only.


Please review our Attribution Requirements.
