    find_federal_grantsFind open U.S. federal grant opportunities an organization is ACTUALLY eligible to apply for. Filters by the machine-readable applicant-type code Grants.gov publishes on every opportunity, so ineligible opportunities are excluded rather than ranked low. Returns deadlines, award ceilings, cost-sharing requirements, and what prior winners of the same program actually received. Free, no key, live federal data.
    check_grant_eligibilityGiven a Grants.gov opportunity ID and an organization type, return a definitive eligibility verdict with the reason. ELIGIBLE / INELIGIBLE / NEEDS_REVIEW. Never guesses: an opportunity that publishes no applicant types, or only 'Others (see text)', returns NEEDS_REVIEW rather than a false green light.
    grant_program_historyWhat a federal grant program has actually awarded before, by CFDA/assistance-listing number: median award, largest award, and recent recipients from USAspending.gov. Use it to sanity-check whether a request is realistic — a $150k ask against a program with a $40M median means competing with major institutions.
