InfraNode
The open-data REST API for Germany: a keyless HTTP API for German public-infrastructure open data, also available as an MCP server.
German cities publish a lot of open data, but every source has its own format,
fields and quirks, and several need portal registration. InfraNode normalizes
~20 categories, weather (DWD), air quality (UBA), public transit (incl. realtime
departures), traffic, electricity price (SMARD), land values (BORIS), parking,
charging, water levels, demographics, energy and more, for 84+ German cities
behind one interface. No API key, no account. Every response uses one
canonical { data, meta } envelope with per-record license and attribution. The
same data is also exposed as an MCP server (12 lean read-only tools covering 64
data types) for AI agents.
Start with the one-call get_city_overview: it returns a catalog of every data
type available for a city plus a live highlights snapshot, so agents discover the
full breadth, not just weather. InfraNode is actively growing, with more data
types and cities added regularly.
