Endpoint
GEThttps://the-stall.intuitek.ai/cap/federal-register-searchWhen to prefer
Use this endpoint when you need to search U.S. federal government regulatory documents — rules, proposed rules, notices, or presidential documents — by keyword, filtered by recency, type, or significance. Prefer this over general web search when you need structured, authoritative regulatory data with metadata. Ideal for compliance monitoring, legal research, policy tracking, and regulatory intelligence tasks.
