Trellis

Trellis (Trellis Research, Inc.) is an AI-powered state and federal trial court research and litigation analytics platform founded by former litigator Nicole Clark. It makes the fragmented U.S. state trial court system — plus federal, appellate, supreme, and bankruptcy courts via PACER — searchable through a single interface, and exposes that data programmatically through the Trellis Trial Court Data API. Law firms, financial institutions, insurers, and researchers use Trellis for case research, judge and ruling analytics, docket monitoring with alerts, document retrieval, business development, lead generation, and due diligence. API access (V2, adding federal + PACER on top of V1 state coverage) is provisioned through a sales-gated free trial.

Trellis publishes 1 API on the APIs.io network. Tagged areas include Company, Legal, Legal Analytics, Court Data, and Litigation.

The Trellis catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Trellis’ developer surface includes documentation, API reference, support, engineering blog, authentication, changelog, and 7 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/trellis: open an issue to ask a question, or submit a pull request to add artifacts.
