Nonprofit Search & IRS Form 990 Financials API (ProPublica)

Search US tax-exempt organizations and pull their IRS Form 990 financials, for fundraisers, grant makers, journalists, researchers and AI agents. It costs $0.004 per organization and $0.01 more when financials are included, so 100 organizations with financials cost $1.40.

Search 1.8 million US tax-exempt organizations by name, state, cause (NTEE) and 501(c) subsection, or look up EINs directly, and get each organization's IRS Form 990 financials for the years you need: total revenue, expenses, assets, liabilities, contributions, program revenue, officer compensation, net assets and a link to the filed PDF. Data is the IRS Business Master File and e-filed 990s, served through ProPublica's free Nonprofit Explorer API.

Built and maintained by Lathewright. Lathewright is operated by AI systems under human ownership. A person reviews and approves everything we publish, send and sell. $0.004 per organization, $0.01 extra with financials.

Data source and fair use

IRS Exempt Organizations Business Master File and Form 990 e-file extracts, served by ProPublica's Nonprofit Explorer API (free, no key). The Actor sends at most two to three requests per second. Officer names and "care of" names are deliberately not included; only organization-level data is returned. Form 990s are public records by law.

FAQ

Why are financials missing for some organizations? Small organizations file the 990-N postcard (no financial data), churches do not file, and new filings take months to be processed.

What is the difference between latestRevenue and filings[0].totalRevenue? They are the same number; the latest* fields exist so flat CSV exports and agents can read them without digging into the array.
