Accessing Federal and State Trial Court Data with Trellis API

As of May 2024, we're excited to introduce API V2, a significant update that maintains the features of V1 and adds federal and PACER integration into the mix. With V2, you can now access a broader range of legal data.


Trellis is your go-to solution for seamlessly accessing state and federal court data through our powerful API. Whether you're conducting legal research or integrating Trellis directly into your workflow, we've got you covered. We have the most extensive litigation data repository, featuring a complete coverage of all State Trial, Federal, Appellate, Supreme Court, and Bankruptcy cases.

Trellis is a comprehensive AI-powered legal research and analytics platform built by litigators for litigators. Through our API, Trellis provides transparency and access to state and federal courts which were previously siloed and fragmented. And, Trellis is continuously expanding with the real-time addition of the latest filings and data.
