About

CharityAPI.org is a simple API for data about US nonprofits and charities sourced directly from IRS filings. It enables developers to retrieve nonprofit records by EIN or Tax ID number, returning the exact information the IRS has on file; perform fast, full-database searches across approximately 1.7 million nonprofit entries; and verify whether a nonprofit qualifies as a public charity with tax-deductible status. The service’s data ingestion pipeline handles all IRS data cleaning, exception management, and JSON conversion, so you can integrate accurate, up-to-date charity information in minutes. CharityAPI.org provides a free tier for registered charities that validate their Tax ID, encouraging companies to offer no-cost services to nonprofit partners, and offers clear, RESTful endpoints and comprehensive documentation to support building donation apps, status-verification workflows, and fundraising platforms efficiently.
