Three interfaces for our corpus
Search and retrieval
Keyword, semantic, and hybrid search over the full corpus, returning ranked passages with the metadata needed to cite them. It also serves the documents themselves, so you can display them in a viewer inside your app — or simply link out to our public content pages instead.
Tools for agents
A hosted MCP server with tools that wrap our API and work in your agent out of the box. Tuned for high-accuracy legal research and efficient use of context. It has no data retention and no lock-in. Customers who have tried both usually get their best results from the MCP.
Dedicated replica
Your own PostgreSQL replica of the whole corpus. Run any query you want against full text, metadata, and the citation graph. Slowest development cycle of the three.
The only API with commercial-grade data quality and coverage
Take a look for yourself: on our coverage page you can navigate through the individual courts and regulations and inspect samples. Our pipeline is fully independently sourced — Midpage is the only data vendor that holds all rights to its content and relies on no data suppliers.
Coverage you can ship on.
All federal appellate and district courts, all state appellate courts, and statutes and regulations from 50 states plus D.C.
Fresh within hours.
New opinions appear the same day they are published, and replicas stay within ten seconds of production.
Compliance already handled.

Support from the people who build it.
Schema documentation, a shared channel, and direct access to the engineers who maintain the pipeline.
The first accurate citator API
It shows which cases are overruled or criticized, and by whom. Building a citator is easy; making it hold up in the hardest edge cases has taken us years. Today it is the most accurate citator ever built, and we will show you the benchmarks.
