Vaquill AI

US primary law as data, built for AI agents and legal products.

We collect statutes, regulations and related primary law from official publishers, normalize it, and serve it through an API and MCP servers. Every section carries its citation, its status (in force, repealed, superseded) and a link to the official source.

Coverage

• Federal: U.S. Code, Code of Federal Regulations, U.S. Constitution, Federal Rules, Federal Register, Statutes at Large and federal agency guidance
• State: statutory codes for all 50 states, DC and Puerto Rico, plus regulations, constitutions, court rules and attorney general opinions where each state publishes them
• 5 million+ sections, refreshed on a schedule

On Apify

• US Primary Law MCP : search, cite and read US law from Claude, Cursor or any MCP client. Pay only for what you use.
