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.

About

CharityBase is a free, open source database and GraphQL API that aggregates fragmented data from the Charity Commission, Companies House, 360 Giving, charity websites, the ONS, and social media into a single, cleaned, normalized, and searchable dataset. It powers a public search portal where users can discover detailed profiles of UK charities, complete with finance, governance, and activity data, and offers a single GraphQL endpoint that responds in structured JSON with custom queries for counts, aggregates, and detailed lists. Designed to eliminate the heavy lifting of data collection and cleaning, CharityBase enables startups, grantmakers, and researchers to build digital tools, such as dashboards, reports, and grant-finding applications, without managing their own data pipeline. Its API supports both GET and POST requests, variable-driven queries, pagination, and live interactive playgrounds for rapid prototyping, all underpinned by regularly updated, audit-trail-backed records.
