How this service works
Search current U.S. Grants.gov opportunities by default, or set source=eu to search English EU Funding & Tenders topics with SEDIA status 31094502. Inputs are source, query, agency, statuses, limit, closing_within_days, and minimum_award_ceiling. Receive up to 20 normalized JSON records with title, agency, status, open and close dates, award amounts, eligibility, funding fields, and official_url.
Output
Returns a list of matching federal grant opportunities including grant title, agency, open/close deadlines, award ceiling, eligibility requirements, and links to official grant sources on grants.gov or equivalent federal portals.
Example use cases
Nonprofit grant deadline monitoring
“Find me up to 15 active federal grants for nonprofits that are closing within the next 30 days — I need the deadlines and official links so I can prioritize applications.”
Research lab funding discovery
“Search for open NSF or NIH federal grants related to climate science or environmental research with a minimum award ceiling of $100,000 and show me up to 20 results.”
Agency-specific grant prospecting
“What federal grants are currently open from the Department of Agriculture? Show me up to 10 active opportunities with their deadlines and eligibility info.”
Technical details
Endpoint
GEThttps://grant-search.46-224-157-88.sslip.io/v1/searchWhen to prefer
Use this endpoint when you need to discover active U.S. federal grant opportunities and want to filter by keyword, sponsoring agency, urgency of deadline, or minimum award size. Prefer this over general web search when you need structured grant data with deadlines and eligibility in a machine-readable format. It is especially useful for agents automating grant prospecting workflows for nonprofits, researchers, or government contractors.
Side effects
- No results returned when query terms are too narrow or misspelled — try broader keywords
- Agency filter returns empty if agency name doesn't match expected format
- closing_within_days set to 0 may return no results if no grants close today
- Result limit must be between 1 and 20; values outside this range will fail validation
- Service may return stale data if federal grant databases haven't been recently indexed
