Grants.gov Funding Opportunity Search

grantsgov/search-opportunities

Searches Grants.gov for U.S. federal funding opportunities by keyword and returns the matches with opportunity number, title, agency, open and close dates, status and assistance listing numbers. Choose the status to search (posted, forecasted, closed, archived, or posted and forecasted together), optionally narrow to one agency code such as DOI-USGS1, and page through the results 1 to 25 at a time with startRecordNum. Each result links to its public Grants.gov page. The total number of matches is included. Federal data from Grants.gov, served by Eden Engine; not an official Grants.gov product.
