How this service works
US federal grant opportunities from Grants.gov matching keywords: number, title, agency, open and close dates (YYYY-MM-DD), status and link, newest opening date first. Grants.gov matches keywords anywhere in the full listing, not only the title. Posted and forecasted opportunities by default. US government data.
Output
Returns a JSON object with the query parameters used, total number of matching grants, and an array of grant records each containing the grant title, number, agency, open/close dates, status, and a direct link to the Grants.gov detail page, plus attribution and the timestamp of the check.
Example use cases
Nonprofit grant discovery
“Find me posted federal grants related to 'affordable housing' — show up to 20 results so I can see what funding opportunities are currently open.”
Research funding search
“Search Grants.gov for forecasted grants about 'cancer research', limit to 10 results, so I can plan ahead for upcoming NIH or NCI opportunities.”
Compliance and audit trail
“Look up archived federal grants matching 'OSHA workforce safety' so I can review what programs were previously funded in this area.”

Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/grants?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search live US federal grant opportunities from Grants.gov by keyword, with optional filtering by status (posted, forecasted, closed, archived) and result count. Prefer this over general web search when you need structured, machine-readable grant data including agency names, dates, grant numbers, and direct links to official government listings.
Side effects
- Missing required 'q' keyword parameter returns a validation error
- Invalid 'status' value (not one of posted/forecasted/closed/archived) may return an error or empty results
- No matching grants returns an empty grants array with total 0
- Upstream Grants.gov API downtime causes request failure
- Limit value outside 1-25 range may be clamped or return an error
