FMCSA QCMobile API is one of 12 APIs that [U.S. Department of Transportation](https://apis.io/providers/us-dot/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Trucking, Motor Carriers, Safety, Compliance, and FMCSA. The published artifact set on APIs.io includes API documentation, a getting-started guide, an API reference, and a support channel.

The Federal Motor Carrier Safety Administration's carrier data API — real-time queries on motor carrier registration, authority and safety data, including all of the passenger carrier data that used to be served by the retired SaferBus API. RESTful, keyed by a free webKey query parameter. This is the only self-serve API credential anywhere in the department: create a Login.gov account, sign in to the FMCSA developer site and generate a key. The developer site publishes a quick start guide, an API access guide, the QCMobile API reference and an API response element reference. FMCSA publishes no OpenAPI.
