How this service works
Search 300,000+ US government datasets on catalog.data.gov (Catalog API): titles, publishing org, formats, and direct resource URLs - the index agents need before fetching public data. ?q=electric+vehicles&rows=5.
Output
A list of matching government dataset records including dataset title, publishing organization, available file formats (CSV, JSON, shapefile, etc.), and direct resource URLs for downloading or accessing the data — essentially an index for agents to know what's available before fetching.
Example use cases
Example prompt
“Search catalog.data.gov for up to 10 government datasets about electric vehicles — I want to see the titles, publishing agencies, available formats, and download URLs.”
Technical details
Endpoint
GEThttps://agent402.tools/api/gov-dataWhen to prefer
Use this endpoint when you need to discover and index US federal government datasets before fetching them — especially when you don't know the exact dataset URL and need to search by topic, agency, or keyword across all 300,000+ entries on catalog.data.gov. Prefer this over direct data.gov API calls when operating in an x402 payment context or when you need a lightweight, agent-optimized search interface.
Side effects
- Empty results if query is too specific or uses uncommon terminology — try broader synonyms
- Rate limit or payment failure if x402 USDC payment is not properly handled
- rows parameter out of range (must be 1-20) returns error
- Stale index if data.gov catalog has been updated more recently than the index
- Network timeout if catalog.data.gov upstream is slow
