Coming soon
Nationwide Full Court Search APIComing soon
A more comprehensive court-records search API extending beyond criminal records: available criminal and non-criminal court proceedings across the United States, including civil cases and additional court record categories. Final record types, jurisdictions and coverage will be confirmed before launch.
The existing Criminal Records API already includes criminal court records. The planned API is a separate product and is not available today.
