How this service works

News for the love of humanity. Evidence-backed U.S. reporting with sources, dates, and room for uncertainty.

Output

Returns a JSON object with a totalMatches count and an array of grant opportunities, each containing a unique grant ID, title, a direct link to the official grants.gov detail page, and the number of days remaining until the deadline.

Example use cases

Nonprofit grant prospecting for climate

“Find me up to 15 open or forecasted grants focused on climate resilience and environmental justice — I want to see what funding is out there right now for our environmental nonprofit.”

Deadline-driven grant search for education

“Search for currently posted grants related to early childhood education and literacy, give me up to 20 results so I can see which ones still have time remaining before they close.”

Eligibility-filtered grants for rural health

“Look up open federal grants for rural health services — we qualify under eligibility code 25 and 20, so filter for those and return up to 10 matching opportunities.”

When to prefer

Choose this endpoint when you need to search U.S. grant opportunities by mission topic or eligibility with evidence-backed sourcing, especially when you want direct links to official grants.gov pages and deadline countdowns. Prefer it over general web search for grants because it returns structured, machine-readable data with official URLs and status filters. It is particularly well-suited for nonprofits and researchers doing programmatic grant prospecting within a specific funding domain.

Side effects

No results returned when keyword is too narrow or misspelled — try broader or synonymous terms
rows parameter must be between 1 and 25; values outside this range will be rejected
Invalid status enum values (e.g. 'open' instead of 'posted') may return errors or empty results
Eligibility codes that don't match any grants will silently return zero results
Service may return stale data if upstream grants.gov sync is delayed
