Is uscodex live?

Yes — it answered the hub's last check (checked 58m ago). It answered 99% of checks over the last 30 days.

Is uscodex free to use?

Yes — the hub reached it with no key and no payment.

What tools does uscodex have?

5 tools: search, fetch, citations, history, compare.

Is uscodex safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• search reads unknown 24h ago

  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 reads unknown 24h ago

  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 reads unknown never probed

  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 reads unknown never probed

  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 reads unknown never probed

  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.
