This ETA API is a part of the rideOS next-generation transportation platform. The API allows you to estimate the time of arrival between several origins and destinations. It computes the estimated time of arrival for a vehicle driving between the specified origins and destinations, while factoring in real-time traffic conditions. In addition to this REST service, there is a gRPC interface for Enterprise customers that should contact the provider for more information. This rideOS API is built on sending a POST request with a JSON body and receiving a response as a JSON object. rideOS provides services to accelerate the global roll-out of next-generation transport.
