Transport for Budapest, Hungary API
Overview
The BKK FUTAR API provides real-time public transport data for Budapest, Hungary, including bus, tram, metro, and trolleybus information. No API key is required, making it easy to start querying schedules and live vehicle arrivals immediately. It is based on the OneBusAway standard, so its structure will be familiar to transit API users.
Beginner Tip
No authentication is needed — start with the /api/where/agencies-with-coverage.json endpoint to explore what the API covers. All responses wrap data inside a "data" key, so remember to navigate into it.
Available Data
The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.
Example Response
Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.
