Tools

• air_quality

  Get official air quality for a German city (PM10, NO2 and more). Sourced from the Umweltbundesamt (UBA). Read-only. For live nearest-station hourly readings use ``get_city_resource(slug, resource='air')`` instead.

  shallow
• compare

  Compare ONE resource across MULTIPLE cities in a single response. Fans the resource out over the listed cities and returns a per-city ``source_status`` (ok/disabled/no_data/error/not_found), so a missing or failing city source does not spoil the whole answer. Read-only.

  shallow
• get_city

  Get base data for a German city (population, area, coordinates). Sourced from Wikidata. Read-only. Useful as a first lookup to confirm a city exists and get its core attributes. For a broader question about the city (what data is available at all) use ``get_city_overview`` instead.

  shallow
• get_city_overview

  Get a ONE-CALL overview of everything InfraNode knows about a German city. Start here for any city question. Returns: the city's base data, a CATALOG of all 81 available data types (weather, air quality, public transit, trains, traffic, charging, parking, solar, energy, demographics, taxes, accidents, tourism, heritage, trees, population density, playgrounds, post boxes and many more), each with its coverage status and the exact tool to call next (for most data types that is ``get_city_resource(slug, resource=<type>)``), plus a small live highlights snapshot (current weather, air quality and train departures). Data types not yet covered for this city show where they ARE available so you can pivot. InfraNode keeps adding data and cities, so the catalog grows over time. Read-only.

  shallow
• get_city_resource

  Fetch ANY per-city data type by its key (generic accessor, 81 data types). One tool for the whole breadth of InfraNode: live data (air, traffic, transit stops, parking, charging, water-level, flood, sharing, fuel-prices, webcams, station-departures/-arrivals/stations, ...), statistics (demographics, unemployment, tourism, accidents, crime-stats, indicators, land-values, tax-rates, insolvencies, ...), multi-year TIME SERIES (``sustainability``: SDG indicators per municipality, one value per year from 2006 to 2023, so trends can be answered without stitching snapshots), infrastructure and environment (solar, solar-roofs, district-heating, energy, heritage, tree-cadastre, playgrounds, public-toilets, markets, education, ...) and more. Discover the valid keys and per-city coverage with ``get_city_overview(slug)`` or the ``infranode://catalog`` resource; the ``resource`` enum lists every key. Uncovered types return ``source_status="not_covered"`` (plus where they ARE available), never an error. Read-only.

  shallow
• list_cities

  List all covered cities (slug, federal state, population, coverage). Takes no arguments. Call this first to discover valid city slugs before invoking any city-scoped tool. Read-only.

  shallow
• pois

  Get points of interest in a German city, filtered by type. Sourced from OpenStreetMap. Read-only.

  shallow
• sources

  List all data sources with license, attribution and availability. Takes no arguments. Shows which upstream sources InfraNode bundles and whether each is currently active. Read-only.

  shallow
• station_board_arrivals

  Get live arrivals for ANY railway station by its EVA number. Mirror of ``station_board_departures`` for arriving trains (all categories, real-time delays, disruption messages). Get the EVA from ``get_city_resource(slug, resource='stations')``. Read-only.

  shallow
• station_board_departures

  Get live departures for ANY railway station by its EVA number. Covers all train categories including local/regional (S/RB/RE) and long distance, with real-time delays, cancellations and disruption messages. Get the EVA from ``get_city_resource(slug, resource='stations')``. Read-only.

  shallow
• transit_departures

  Get live public-transport departures with real-time delays for a stop. Sourced from GTFS-RT/HVV/VGN. Unlike the static stop list (``get_city_resource(slug, resource='transit')``), this returns minute-fresh departures including delay for ONE stop. A ``stop_id`` is required: fetch the city's transit stops first to discover valid stop IDs, then pass one here. Read-only.

  shallow
• weather

  Get current weather observations for a German city. Sourced from the Deutscher Wetterdienst (DWD): temperature, wind, precipitation and related fields. Read-only, current conditions only (not a forecast). For warnings use ``get_city_resource(slug, resource='weather-warnings')``. For a broader question about the city (not just weather) use ``get_city_overview`` instead, which already includes a live weather highlight.
