Federal Register Rules, Regulations & Proposed Rules API

Search official Federal Register documents for final rules, proposed rules, notices, agency actions, comment deadlines, dockets, RINs, and CFR references. Deterministic test: query=artificial intelligence&maxResults=1. Records can be corrected, republished, withdrawn, delayed, or superseded and are publication evidence—not legal advice, current codified-law or applicability proof, or proof a reported comment deadline remains open. MCP tool: search_federal_register_documents.
