Search Grantmakers
search_fundersRead-only
Look up grantmaking organizations by name, topic, or location.
This tool searches 174K+ grantmaking organizations from IRS data using organization names plus grant-purpose/topic signals. Use it when you know the funder's name, want aligned funders for a cause area, or want to browse by location/size/NTEE code. Multi-word searches are ranked by relevance; simple browse/name fallback results are ordered by total assets.
IMPORTANT: Use search_open_grants when the user needs active grant programs or RFPs. search_funders is for finding aligned grantmakers, including ones that may fund by relationship, LOI, or annual cycle rather than a live call.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| city | No | City name to filter by (case-insensitive). Example: "San Francisco", "New York" | |
| limit | No | Maximum number of results to return (1-50) | |
| metro | No | Colloquial metro / region name for sub-state geography a single city can't capture — "Bay Area", "NYC", "the DMV", "Greater Boston", "Los Angeles", "Chicago", "Seattle". Resolved to its MSA/CBSA code set and applied as an HQ pre-filter. PREFER this over `city` whenever the user names a metro/region rather than one municipality (e.g. "Bay Area funders that fund drug rehab" → query="drug rehab addiction", metro="Bay Area"). Accepts a single name or a list. City names resolve too ('Cleveland', 'Knoxville', 'Portland, OR'). An unrecognized name does NOT error: the search runs without that metro filter and the result carries `geo_notice` saying so (with a did-you-mean when one is close). Example: "Bay Area", ["NYC", "Greater Boston"] | |
| query | No | Search term for a funder name or cause-area phrase. Example: "Ford Foundation", "global health", "community foundation" Topic searches work best with 2+ words. | |
| state | No | Two-letter US state code to filter by funder HQ location. Example: "CA", "NY", "TX" | |
| country | No | Optional HQ country name (or list of names) to restrict to funders headquartered in those countries (e.g., "Germany", ["United States", "Canada"]). Distinct from `grantee_country_codes` (where the funder's grants land) and from `state` (US state of HQ). Use when the user asks for funders based in a specific country — e.g. "European-headquartered foundations" → country=["Germany","Spain","United Kingdom", "Switzerland","Netherlands","France"]. US foundations are included only when "United States" (or "USA") is in the list, or when the param is omitted. | |
| has_pris | No | Filter to foundations with known program-related investment activity. Set true when looking for PRI-active capital providers. | |
| msa_codes | No | Explicit MSA/CBSA codes when you already know them (e.g. ["41860", "41940"]); unioned with whatever `metro` resolves to. Most callers should use `metro`. | |
| ntee_code | No | NTEE classification code to filter by. Example: "A20" (Arts Organizations), "B" (Education), "E" (Health) | |
| max_assets | No | Maximum total assets filter in dollars. Example: 100000000 (foundations with up to $100M assets) | |
| min_assets | No | Minimum total assets filter in dollars. Example: 10000000 (foundations with $10M+ assets) | |
| funder_type | No | Optional canonical funder_type to include. Examples: "community_foundation", "family_foundation", "corporate_foundation", "private_operating", "operating_nonprofit", "independent_foundation". Use this to narrow to a specific kind of grantmaker. NOTE: operating entities (private_operating, operating_nonprofit) are EXCLUDED BY DEFAULT — name one here to include it (e.g. to look up a specific hospital or patient-assistance foundation). | |
| has_er_grants | No | Filter to foundations that make expenditure responsibility grants (grants to non-501(c)(3) entities like PBCs, for-profits, and foreign orgs). Set to True to find only ER-active funders. | |
| exclude_funder_types | No | Optional list of canonical funder_type codes to exclude from results. NOTE: this search ALREADY excludes the operating-entity types by default — private_operating (pharma patient-assistance foundations) and operating_nonprofit (hospital / university group returns) post large "annual_grants" but aren't grantmakers you can apply to. Use this for ADDITIONAL categories; to opt an operating type back in, name it in funder_type instead. | |
| grantee_country_codes | No | Optional list of FIPS 10-4 country codes (e.g., "UK" for United Kingdom, "IN" for India, "KE" for Kenya, "SF" for South Africa) to restrict to funders whose grantees are located in those countries. Use this when the user is asking for funders that move money into a specific non-US geography. Country here is the grantee's HQ country, derived from foundation_grants. When set, the search is forced through the hybrid path; the ILIKE-only name-match path cannot filter by country. Distinct from `state`, which filters by the funder's own US HQ. |
