Programmatic API exposing every grant in e-filed US 990 filings as a funder-grantee graph.
The Grants API itemizes every grant reported in e-filed United States Forms 990, 990-EZ, and 990-PF, resolving roughly 211,000 funders and more than 20 million grants across fiscal years 2017 through 2026 into a queryable funder-grantee graph.
Endpoints cover aggregate summaries, ranked funders and recipients, and individual transactions with filters for year, geography, cause, and amount, provenance scoring on every recipient EIN, and free and paid key tiers, and the service documents a migration path from the Candid Grants API.
