## Tool descriptions

- `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 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…
- `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 availab…
- `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, …
- `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…
- `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.
- `pois` — Get points of interest in a German city, filtered by type. Sourced from OpenStreetMap. Read-only.
- `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.
- `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'). R…
- `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_reso…
- `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 …
- `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_resour…

## For agents
