Why Lawstronaut for US legal research
US legal information is spread across the federal statute code, the Code of Federal Regulations, the Federal Register, Congress, dozens of federal agencies and regulators, and the federal courts — with a separate body of law in each of the fifty states. For humans, that means slow research. For AI systems, it's a bigger problem: fragmented source access, inconsistent formats, missing provenance, and weak citation trails.
Lawstronaut turns those sources into one structured legal data layer — source links, metadata, full text, versioning, and API/MCP access. Your product or agent retrieves the legal source directly instead of relying on generic web search or unverified model memory. Every answer carries a citation, a timestamp, and a link to the official document — the provenance that makes a legal research platform defensible to auditors and regulators.
About United States legal coverage
The United States is a common-law, federal jurisdiction. Federal statutes are codified in the United States Code (U.S.C.) on uscode.house.gov, federal regulations appear in the Code of Federal Regulations (eCFR) and are published daily in the Federal Register, and legislative materials — bills, resolutions, and committee documents — sit with Congress on congress.gov and GovInfo. Case law comes from the Supreme Court of the United States and the federal courts of appeals and district courts, available through official sources and CourtListener. Regulatory guidance and enforcement sit with agencies such as the SEC, FTC, CFPB, OSHA, IRS, and the Federal Reserve. Records are published in English, and the law of individual US states is covered as separate jurisdictions.
US federal law moves quickly: the Federal Register publishes new rules and notices every business day, agencies issue a continuous stream of guidance and enforcement decisions, and fast-moving areas — financial regulation, data privacy and AI, immigration, and employment — change from one administration and Congress to the next. Point-in-time data straight from the source is what keeps a US legal research answer correct today.
