How this service works
Pay-per-call company registry, government, legal and B2B data tools for AI agents, from official registers and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.
Output
Returns a JSON object with the source URL, keyword used, timestamp, total number of matching opportunities, and an array of opportunity listings each containing: opportunity ID, title, funding agency name, opportunity number, status (posted/forecasted/closed), open date, close date (if set), and an array of associated CFDA numbers.
Example use cases
Researcher scouting NSF funding
“Can you search federal grant opportunities on Grants.gov for 'quantum computing' and return the top 5 results with funding agency, status, and close dates?”
Nonprofit finding healthcare grants
“Look up open federal grant opportunities related to 'maternal health' on Grants.gov — I need the opportunity titles, agencies, and CFDA numbers for up to 10 results.”
Policy analyst tracking climate funding
“Search Grants.gov for forecasted and open grants about 'climate resilience' — show me the opportunity numbers, agencies, and whether each one is still open or just forecasted.”
Technical details
Endpoint
GEThttps://api.companyrecords-api.workers.dev/api/gov/grants-gov?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover active or forecasted US federal grant opportunities by topic keyword, especially when you need structured data including CFDA numbers, agency names, and open/close dates. It surfaces opportunity listings only — not award decisions or recipient data — making it ideal for grant prospecting workflows. Prefer this over manual Grants.gov searches when integrating grant discovery into automated research or funding pipelines.
Side effects
- Keyword too short (under 3 characters) or too long (over 60 characters) returns a validation error
- Grants.gov search2 API upstream outage causes failure or empty results
- No matching opportunities found returns totalHits of 0 and an empty opportunities array
- Limit parameter out of range (outside 1-10) may return default of 5 or an error
- Results reflect Grants.gov index state at crawl time and may lag real-time status changes
