Transport for Finland
Digitransit is HSL and the Finnish Transport Infrastructure Agency's shared open-source journey-planning platform, offering a GraphQL Routing API for itineraries plus stop/timetable queries and a separate Geocoding API for address search, both backed by nationwide GTFS data. Production use of api.digitransit.fi requires free registration for a subscription key, with quota-based rate limiting introduced to curb abuse rather than to monetize the API.
