Open data API for 84 German cities

InfraNode covers 84 German cities with more than 100,000 inhabitants. Of these, 28 are core cities with curated, hand-verified source coverage (badge Core). The remaining cities (badge Auto) are served via AGS- and geo-based sources; where a hand-curated source returns nothing for them, the API answers honestly with no_data instead of an error.

The machine-readable list of all cities is available via GET /api/v1/cities:

curl https://infranode.dev/api/v1/cities

One slug, every endpoint

The 29 city endpoints work per city through the same slug. Just drop the slug from the table into the path, for example for Berlin. On top of these there are live endpoints, some of them city-specific (for example Cologne traffic conditions, Berlin traffic messages) plus public-transit real-time for all cities:

You don't need the exact slug: the city name is resolved leniently. The German name with or without umlauts, any casing, and common English exonyms and short forms all resolve to the same city (München, münchen, munich, munchen all resolve to muenchen, cologne to koeln, frankfurt to frankfurt-am-main). An unknown name returns a 404 whose hint suggests the closest slug (“Meintest du …?").
