}search_funders — Search foundations
Search the foundations that have a public GrantCue profile (built from the latest Form 990-PF, or Form 990 Schedule I for community foundations and other grantmaking charities), largest givers first. Search by name, city, state or EIN, by the state they mainly give to, or for those that publish how to apply. Form 990 grantmakers are found by name, state or EIN, after the 990-PF matches, each marked source_form "990". Returns 10 per page.

}get_funder — Get a foundation
A foundation’s public GrantCue profile, from the latest Form 990-PF, or Form 990 Schedule I for community foundations and other grantmaking charities: giving totals, typical and median grant, giving by year, where it gives, the 25 largest grants its latest filings report, and for a 990-PF filer how to apply. For a Form 990 funder: its kind, the latest tax year, totals and the top 10 recipients (yearly totals); Form 990 does not say whether it accepts applications. Only foundations with a public profile, and funders with a Schedule I return, are found. It never returns the full list of reported grants.
