Technical details
Endpoint
POSThttps://x402.datakoot.com/api/search_documents?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search official US Federal Register content including rules, proposed rules, notices, and presidential documents — especially when filtering by agency, date range, or document type matters. Prefer this over general web search when you need structured, authoritative regulatory data with direct PDF and HTML links to official government sources.
Side effects
- Invalid agency slug returns no results or error — use the agencies tool first to get valid slugs
- Dates in wrong format (not YYYY-MM-DD) may cause errors or unexpected results
- Very broad keyword searches may return thousands of results requiring pagination
- Misspelled keywords return empty result sets
- Invalid document type enum value causes request rejection
