Hello Developer

Welcome to the Charity Navigator API portal. At this site you can signup, get a key, access analytics, change plans, etc.

We have ratings for nearly 7,000 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). Our API provides developers access to our high-quality, comprehensive charity data which can be easily integrated into your application or website.

NEW: We've just added the entire database of IRS registered nonprofits to our API. You can perform simple searches based on name/state/ein to lookup basic information for any of the 1.6 million nonprofits registered with the IRS.

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 (Premium Feature)*

*Applies to rated organizations only.

Upon initial signup, you will be granted access to the Basic package. If you are interested in the Premium package, please contact us via api@charitynavigator.org.
