🟢search(corpus, date, page, query, title)
Search the full text of federal law: United States Code, Code of Federal Regulations, Public Laws, Congressional Bills, Executive Orders. Results are ranked across every corpus unless `corpus` narrows them, each with its citation, a link and the matching words. A query that is only a citation returns that document instead.

}🟢fetch(citation, notes, path, provision, release)
Read a document or page of the site as markdown: a code section with its notes, a title's or unit's contents, a public law, a bill (at any version), an executive order. Paths also reach the corpus indexes ("/usc", "/pl?congress=118", "/bills?congress=119", "/eo") and each code's releases ("/usc/releases"). Links in the markdown are paths this tool accepts.

}⚪citations(citation, list, offset, path)
What cites a document: each corpus's citations of a code section, law, bill or order, with the words that cite it, and for a statute the regulations issued under it. Lists come 50 at a time; `list` and `offset` page through one.

}⚪history(citation, path)
How a document came to be: for a code section, the laws that enacted and amended it and every release that changed its text; for a law or bill, its legislative history, each version linked to its text and to what changed from the one before.

}⚪compare(citation, from, only_edits, path, to)
What changed in a code section between two releases: each provision added, removed, changed or renumbered, the edits marked <del> and <ins>. To compare versions of a bill, take the 'what changed' link from its history.
