🟢search_grants(keyword, eligibility, include_unrestricted, categories, instruments, ...)
Search live federal funding opportunities on Grants.gov. Results come from Grants.gov, and users must confirm every detail on the official listing before applying; each result carries its listing link. Filter by keyword, applicant type (small businesses, 501(c)(3) and other nonprofits, tribes, local governments, individuals and more), category, award instrument, agency, Assistance Listing number, status (posted by default, or forecasted) and close date range. Returns the total matches and each listing with id, number, title, agency, posted and close dates, days left and URL. Sort by relevance (default with a keyword), closing_soonest (default without one) or newest. Results are cached for 10 minutes.
