The complete Grants.gov database — 83,367 opportunities from 49 grant-making agencies going back to 2003, including all currently posted opportunities and agency forecasts — synced nightly from the official full-database extract. Each grant carries its full profile: opportunity number, agency, funding instruments (grant / cooperative agreement), funding categories, CFDA/Assistance Listing numbers, decoded applicant eligibility (small businesses, 501(c)(3) nonprofits, institutions of higher education...), award ceiling/floor, estimated total program funding, expected award count, cost-sharing flag, key dates and the full description. Status (forecasted / posted / closed / archived) is derived from dates at query time so it never goes stale — our posted and forecasted counts match Grants.gov's own search to within a day's drift. Full-text search over titles AND descriptions ('wastewater infrastructure' finds the EPA workforce grants), filter by status, agency, funding category, eligibility, CFDA number, minimum award ceiling or post date, and look any opportunity up by ID or number.
