Court Rules API API

Overview

Court Rules is a free reference for U.S. federal court practice: the Federal Rules of Civil Procedure, district local rules, individual judge standing orders and court holidays, organized by court. The deadline calculator counts calendar, business and court days and applies each district's holidays. A public API and an MCP server at courtrules.app/mcp serve the same data to legal-tech tools.

Court Rules API is a government API. It needs no API key. It is served over HTTPS.
