air_quality
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.

compare
Compare Cities
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.

get_city
City Base Data
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.

get_city_overview
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.

get_city_resource
City Data by Type
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.

transit_departures
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.

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
