How this service works
Pay-per-call search of public US government data. Unofficial; verify at source. Provided AS IS with no warranty of any kind, express or implied, including accuracy, completeness, timeliness, merchantability or fitness for a particular purpose. Not affiliated with or endorsed by any U.S. government agency.
Output
Returns a JSON object containing an array of grant opportunity records (each with ID, title, agency, ALN codes, opportunity number, document type, open/close dates, and status), a total hit count, a cache hit/miss indicator, the source URL, and disclaimer/notice text confirming the unofficial nature of the data.
Example use cases
Nonprofit finding education grants
“Can you search federal grants for 'early childhood education' and show me the first 10 results, including which agencies are offering them and when they close?”
Researcher tracking climate funding
“Look up federal grant opportunities related to 'climate resilience' — give me up to 25 results from page 1 with their statuses and deadlines.”
Tribal organization seeking broadband funding
“Search for federal grants about 'tribal broadband' and list the opportunities you find, including their grant numbers and open and close dates.”
Technical details
Endpoint
GEThttps://test5-x402-gov.stackstats.workers.dev/grants/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically search US federal grant opportunities by keyword and receive structured JSON results with agency, deadline, and status metadata. Prefer it over scraping Grants.gov directly when you need a pay-per-call API interface with a predictable schema. Note that it is unofficial and results should be verified at source; it is not suitable when authoritative, legally binding data is required.
Side effects
- Missing required 'q' query parameter returns a 400 error
- Search keyword exceeds 200 characters causes rejection
- Page number outside 1–5 range causes validation error
- Limit value outside 1–25 range causes validation error
- Upstream Grants.gov API unavailable causes failure or stale cache
- Payment not attached or insufficient USDC causes 402 rejection
- Results may be incomplete or delayed relative to official Grants.gov listings
