FMCSA QCMobile API
The FMCSA QCMobile API provides safety performance data for U.S. Department of Transportation registered motor carriers. Developers can query carrier registration information, licensing, insurance, operating authority, and BASIC safety scores by U.S. DOT number, MC docket number, or carrier name. All responses are returned in JSON format. Access requires a developer account and API webkey obtained through Login.gov.
