Fetch the authoritative current text of any United States Code section by title and section number — for example title 17, section 107 returns the fair-use statute. Returns the canonical citation, heading, hierarchy context (title/chapter), full statutory plain text, the Statutes-at-Large source credit, and a link to the official OLRC page; set includeNotes=true to also get editorial notes (amendment history, effective dates). Hyphenated and lettered sections like 1395w-4 or 78j work. Data from the Office of the Law Revision Counsel current ("prelim") edition, public domain — verify statutory citations against the authoritative source instead of relying on model memory.
