# Trellis Research

> Trellis (trellis.law) is an AI-powered state and federal court research and litigation analytics platform. It aggregates the most extensive U.S. trial court data available — State Trial, Federal, District, Appellate, Supreme Court, and Bankruptcy cases across all 50 states plus DC — and exposes it through Smart Search, a REST Data API (V2), and a remote MCP server for case, docket, document, ruling, verdict, judge, party, and expert research plus litigation analytics.

This llms.txt was generated by the API Evangelist enrichment pipeline from the provider's public documentation (the trellis.law site is behind bot protection). Values marked as behind the sales-gated reference are not reproduced.
