What Is the Public Transit API v3?
The Public Transit API v3 is a REST API that allows you to use agency data, external services and data collected by HERE to discover public transit options, request public transit routes and transit related information.
The Public Transit API has a number of endpoints that center around two major features:
- Discovery - shows stations and departure of transit services around a given location, transit stations that could be reached within a certain time frame from a given location and shows transit line(s) details at any given station
- Routing - provides the most efficient and relavant transit routes between a given pair of locations.
