American Case Law

A simple app to browse, search, and access a comprehensive database of American caselaw. This app is powered by the Caselaw Access Project (CAP) API developed by the Library Innovation Lab at Harvard University and Ravel Law.

Note that access is currently restricted to 500 cases per day for many jurisdictions. To access full cases, you will need a CAP API key, which you can get by creating a free account with CAP. Once you have registered, you can find your key by visiting your account page.

Paste your API key in the box on the top right-hand corner of the page to get full access to cases found in the Caselaw Explorer.

This front-end application was developed by the Jack Miller Center in support of the study and teaching of America's founding principles and history.
