Grants.gov Federal Grants Search API: US federal grant opportunities as clean data

For grant writers, nonprofits, universities, small businesses, consultants and funding-research teams who need to find US federal grants without clicking through the Grants.gov search page. Search by keyword, agency, applicant type and category and get one flat row per opportunity with deadline, award amounts and a short synopsis. $1.50 per 1,000 opportunities.

Try it free: leave input empty and press Start. The demo returns a few current opportunities and is never charged.

number	title	agency	status	closeDate	awardCeiling
HHS-2026-ACF-0000	Community Resilience Program	Administration for Children and Families	posted	2026-12-15	500000
DE-FOA-0003000	Grid Modernization Projects	Department of Energy	forecasted	2027-02-01	2000000

(Illustrative sample. Award fields appear when includeDetails is on.)

• Official API: uses the public Grants.gov REST API (search2 and fetchOpportunity), no login, no API key, no scraping.
• Filters: keyword, statuses (forecasted, posted, closed, archived), agencies, eligibilities (applicant types), funding categories, posted date range.
• Optional details: includeDetails adds award ceiling and floor, estimated total funding, number of awards, categories, eligibilities and the synopsis.
• No personal data: agency contact names, emails and phone numbers are never output.
• Polite: one request at a time, at least 1 second apart, identifiable User-Agent, backoff on 429 and 5xx.

Unofficial: not affiliated with Grants.gov, the General Services Administration or the US government.

Input

{
  "keyword": "wildfire",
  "oppStatuses": ["posted", "forecasted"],
  "agencies": ["HHS", "DOE"],
  "eligibilities": ["25"],
  "fundingCategories": ["HL"],
  "postedFrom": "2026-09-01",
  "postedTo": "2026-10-31",
  "includeDetails": true,
  "maxItems": 50
}

• oppStatuses: any of forecasted, posted, closed, archived (empty = forecasted + posted).
• agencies, eligibilities, fundingCategories: Grants.gov codes, one per line (see the field descriptions for common codes).
• postedFrom / postedTo: YYYY-MM-DD, compared with the opportunity's open (posting) date. Applied by the Actor after the search, so a narrow range on a very large result set scans more pages (up to 3,000 search hits per run).
• maxItems: 1 to 1,000 (default 10).

Output (one item per opportunity)

{
  "id": "350000", "number": "HHS-2026-ACF-0000", "title": "Community Resilience Program",
  "agency": "Administration for Children and Families", "agencyCode": "HHS-ACF",
  "status": "posted", "openDate": "2026-09-01", "closeDate": "2026-12-15",
  "awardCeiling": 500000, "awardFloor": 10000, "estimatedTotalFunding": 2000000, "expectedNumberOfAwards": 4,
  "categories": ["Health"], "eligibilities": ["Nonprofits having a 501(c)(3) status with the IRS, other than institutions of higher education"],
  "synopsis": "Funds community projects that ...",
  "url": "https://www.grants.gov/search-results-detail/350000"
}

• Without includeDetails, award fields, categories, eligibilities and synopsis are empty (the search call does not return them).
• synopsis is plain text, cut at 2,000 characters.
• A run summary (total matches, scanned, returned, errors) is saved to the key-value store as SUMMARY.

Pricing

Pay per event: $0.0015 per opportunity returned (1,000 opportunities cost $1.50). The empty-input demo and failed runs are free. includeDetails makes one extra API call per opportunity (about 1 second each) but does not cost extra. Set a max charge per run in the run options to cap spend.

Use cases
