Use when asked about step-free access or a broken lift: "Funktioniert der Aufzug am Kölner Hauptbahnhof?", "is the lift at Hamburg Hbf working?", "Rolltreppe am Neumarkt kaputt?", wheelchair, pram, heavy luggage. Do NOT use for train times, platforms or delays — call get_train_departures. At most 50 facilities, out-of-service ones first. Results carry their attribution line.
Whether the lifts and escalators of a railway station or Köln Stadtbahn stop work now: each one, its place, state and reason. Another tram, U-Bahn or bus stop (named with its city: "Stuttgart Charlottenplatz") gets its step-free survey where one exists. Use when asked about step-free access, broken lifts, wheelchair or pram: "Funktioniert der Aufzug am Kölner Hbf?", "is the lift at Hamburg Hbf working?". Do NOT use for departures, platforms or delays — call get_train_departures (trains) or get_departures (bus, tram, U-Bahn). At most 50, broken first. Results carry their attribution line.

Use when asked whether buses and trains run normally, or a strike, storm or works disrupt them. Do NOT use for a station's departures or a line from a named DEPARTURE station ("RE1 ab Köln Hbf verspätet?"; a destination, "nach …"/"zum …", is not one) — get_train_departures. No per-line figures.

find_addresschangeddescriptionLooks up a street address: its coordinate, and the named OpenStreetMap objects at it (company, shop, office) or that none are. Use when the person gives a STREET AND NUMBER — "Bahnhofstraße 12, Fulda" — for the point, or for who or what is there. The coordinate passes to any other tool as lat/lon. Do NOT use for a town/district/station name alone (find_place) or a company/shop/landmark by name (find_poi) — needs a street and a number. At most 5 points; a door mapped twice is folded, points far apart say how far; several towns are a question. OpenStreetMap ODbL 1.0; show the attribution line.

find_placechangeddescriptionLooks up a place name and returns every place that matches, each with its kind, official key (AGS/RS), population, English name and coordinate. Use when the person asks where somewhere is, when you need a coordinate for another tool, and above all to RECOVER after a tool reported a name as ambiguous — this is where you find out which Neustadt is which. Pass `near` to rank and separate same-named places by distance. Do NOT use to find a company, shop or landmark: call find_poi. At most 10 results, radius <= 200 km. Every result carries an attribution line that must be shown to the user.

find_hydrogen_stationchangeddescriptionReturns hydrogen (H2) filling stations near a place or coordinate, nearest first, with operator, address, pumps (700 bar car, 350 bar truck/bus), opening hours where published and the age of the record. Use when someone asks where to refuel a fuel-cell car, lorry or bus ("Wasserstofftankstelle", "H2 tanken", "hydrogen station near me"). Do NOT use for petrol, diesel or LPG (call find_fuel_station) or EV charging (call find_charging_station). Radius ≤ 150 km, ≤ 10 stations; no live availability or price is published.

Use when a date or window is named, it says geplant, or how long a site lasts ("Baustellen auf der A7 in den Sommerferien?"). ONE road/place per call. Do NOT use when more than one motorway is named, for the situation this minute, or for Baustellen with neither date nor geplant — all three are check_autobahn_traffic; whether a road is open — check_road_status. ≤ 92 days, max 20 sites.

check_road_statuschangeddescription, input schemaWhether a motorway, B or Land road (NI, SN, TH, BW: pass the Land/town as place) is open, closed, restricted, now or coming days; by place, jams, city/Land messages, Hamburg traffic cameras. Use when asked if a road is open/passable — "ist die A8 in diesem Moment gesperrt", "komme ich durch", at any clock, closures tonight/weekend — or city Stau: "Stau in Köln?". Do NOT use for jams/delays on a named motorway or multi-motorway route — check_autobahn_traffic; roadworks in a date window — find_roadworks_ahead; city street: not held, say so. ≤ 14 days, ≤ 11 entries.

check_autobahn_trafficread-only | Jams, slow traffic, closures and roadworks in force this minute on up to 5 motorways, with delay/speed. Use when asked about a named motorway now: Stau, a delay, how it looks, or a LIST of closures now; name every motorway (Munich→Berlin: A9). Do NOT use for yes/no: is a road open/closed/passable — check_road_status, even now — nor a closure with no time word or a later one (tonight, weekend); Baustellen dated or geplant — find_roadworks_ahead; Stau in a town, no motorway — check_road_status; fuel (find_cheapest_fuel), trains (get_train_departures). ~5 min old. Show the attribution line. |
check_road_statusread-only | If a motorway, B/Land road (NI, BW, MV, SN, TH; B also SH, BY, BE; pass Land/town as place) is open/closed/restricted now/next days; by place, jams, city/Land messages, Hamburg traffic cameras; lorry limits, Lang-Lkw (vehicle). Use when asked if a road is open/passable — "ist die A8 in diesem Moment gesperrt", at any clock, closures tonight/weekend — or city Stau: "Stau in Köln?". Do NOT use for jams/delays on a named motorway or multi-motorway route — check_autobahn_traffic; roadworks by date window — find_roadworks_ahead; city street: not held, say so. ≤ 14 days/11 entries. Show attribution. |
check_station_facilitiesread-only | Whether the lifts and escalators of a railway station or Köln Stadtbahn stop work now: each one, its place, state and reason. Another tram, U-Bahn or bus stop (named with its city: "Stuttgart Charlottenplatz") gets its step-free survey where one exists. Use when asked about step-free access, broken lifts, wheelchair or pram: "Funktioniert der Aufzug am Kölner Hbf?", "is the lift at Hamburg Hbf working?". Do NOT use for departures, platforms or delays — call get_train_departures (trains) or get_departures (bus, tram, U-Bahn). At most 50, broken first. Results carry their attribution line. |
check_transit_disruptionread-only | How punctual public transport is now in one German region: the share of trips ever >5 min late, trips skipping a stop, trips cancelled, the trend and the service alerts in force there (diversions, closed stops). Use when asked whether buses and trains run normally, or a strike, storm or works disrupt them. Do NOT use for a station's departures or a line from a named DEPARTURE station ("RE1 ab Köln Hbf verspätet?"; a destination, "nach …"/"zum …", is not one) — get_train_departures. No per-line figures. Window ≤ 120 min. CC BY-SA (DELFI) or CC BY 4.0 (VBB, Berlin/Brandenburg): show attribution. |
check_weather_warningsread-only | Returns the official DWD weather warnings in force for a place — storm, snow, ice, heavy rain, thunderstorm, heat — with Warnstufe 1–4, area, validity and the official text unaltered. At a town or coordinate it adds the DWD road-surface forecast (Straßenwetter-Prognose: dry to black ice, road temperature) for the nearest road-weather stations. Use when asked about weather on a trip, safe driving, storm or snow warnings, or icy roads (Glätte, Glatteis). Do NOT use for a general forecast (not offered) or jams (check_autobahn_traffic). Show the attribution line. |
describe_locationread-only | Turns a coordinate into words: the nearest address, settlement and motorway junction with their distances, and the Gemeinde, Kreis and Land the point lies in; also any low-emission zone. Use when you already HAVE a lat/lon and need to say where that is. Do NOT use to look up a place or address BY NAME — that is find_place, find_poi or find_address; this only goes coordinate to words. Those come from the municipality the point lies in (its key), not the nearest Kreis point; near the border the answer says so. OpenStreetMap ODbL 1.0 for the address; show the attribution line. |
find_addressread-only | Looks up a street address: its coordinate, and the named OpenStreetMap objects at it (company, shop, office) or that none are. Use when the person gives a STREET AND NUMBER — "Bahnhofstraße 12, Fulda" — for the point or the business there, never who lives there. The coordinate passes to any other tool as lat/lon. Do NOT use for a town/district/station name alone (find_place) or a company/shop/landmark by name (find_poi). At most 5 points; a door mapped twice is folded, points far apart say how far; several towns are a question. OpenStreetMap ODbL 1.0; show the attribution line. |
find_charging_stationread-only | Returns EV charging sites near a place or coordinate with operator, connector types, maximum power, price per kWh where published, and how many points are free right now where the operator publishes live status. Use when an EV driver asks where to charge ("Wo kann ich laden?", "CCS 150 kW near Leipzig", "ist gerade eine Säule frei?"). Do NOT use for petrol or diesel — call find_cheapest_fuel; for E-Kennzeichen or Ladekarte rules — call get_driving_rules. Radius ≤ 25 km, ≤ 10 sites; availability is missing for most operators and is then unknown, never free. Show the attribution line. |
find_cheapest_fuelread-only | Returns the cheapest stations for one fuel grade near a place or coordinate: price per litre, brand, address, distance, open state. Use when the user asks where to fill up or what fuel costs. Do NOT use for charging an electric car (call find_charging_station), price history, or traffic (call check_autobahn_traffic). Radius ≤ 25 km, at most 10 stations. For a brand, a name, open now or at a named time, or nearest-first, call find_fuel_station. Each line names the age of its price and opening-hours claim. Prices are consumer information only; the attribution line and MTS-K note must be shown. |
find_fuel_stationread-only | Finds filling stations around a place or coordinate under any combination of filters — grade, brand, name, open now, open at a time you name, open 24 h — sorted by distance, price or name. Use when the question is WHICH station: the closest diesel to a stop, an ARAL open tonight, what one forecourt sells. Do NOT use for the plain "where is fuel cheapest" question (call find_cheapest_fuel) or for charging an electric car (call find_charging_station). Every result carries the attribution and the MTS-K note, and says how old each price and opening-hours claim is. |
find_hydrogen_stationread-only | Returns hydrogen (H2) filling stations near a place or coordinate, nearest first, with operator, address, pumps (700 bar car, 350 bar truck/bus), opening hours where published and the age of the record. Use when someone asks where to refuel a fuel-cell car, lorry or bus ("Wasserstofftankstelle", "H2 tanken", "hydrogen station near me"). Do NOT use for petrol or diesel (call find_fuel_station) or EV charging (call find_charging_station); LPG/Autogas and CNG are not held — say so. Radius ≤ 150 km, ≤ 10 stations; no live availability or price is published. Shows the attribution line. |
find_nearbyread-only | Overview of what is around a place or coordinate: nearby fuel stations, EV charging, parking, the nearest railway station and motorway junction, each with its distance. Use when someone asks "what is around me" or "what is near <place>" — a broad look, not one category in depth. Do NOT use for a fuel grade's price (find_cheapest_fuel), charger/connector status (find_charging_station), parking kind/occupancy (find_parking), a NAME lookup (find_place/find_poi/find_address), or a coordinate's address (describe_location). Radius ≤ 15 km, up to 3 per category. Shows each source's attribution. |
find_parkingread-only | Parking near a place, a coordinate or along one motorway: lorry parks, car parks, P+R and disabled-badge bays, with total spaces and, where published, free spaces now and the reading's age. Use when asked where to park or leave the car for the train ("Parkhaus in Köln", "Rastplatz A3", "P+R"). Do NOT use for fuel (find_cheapest_fuel) or EV charging (find_charging_station). Radius ≤ 25 km, ≤ 10 sites per list; ODbL and CC BY-SA sources are separate lists (up to three). No "free now" means no published count, not full. No prices: for "was kostet" say so, no call. Show each source's attribution. |
find_placeread-only | Looks up a place name and returns every match, each with its kind, population, English name and coordinate; the official key (AGS/RS) only in the structured result. Use when the person asks where somewhere is, when you need a coordinate for another tool, and above all to RECOVER after a tool reported a name as ambiguous — this is where you find out which Neustadt is which. Pass `near` to rank and separate same-named places by distance. Do NOT use to find a company, shop or landmark: call find_poi. At most 10 results, radius <= 200 km. Every result carries an attribution line to show the user. |
find_poiread-only | Finds a business or landmark by name or kind — company, shop, clinic, hotel, hostel — with address, category and coordinate. Use when the person names a THING rather than a town: "the adesso office in Dortmund", "the nearest Aldi", "a hotel in Weimar". The coordinate passes to any other tool as lat/lon. Do NOT use for a town, district or station (every tool's `place` resolves those), nor for fuel, charging or parking (own tools). Give "in" (a town) when you can: far faster than nationwide. 25 per page, 50 via cursor; radius <= 50 km. OpenStreetMap under ODbL 1.0; show the attribution line. |
find_roadworks_aheadread-only | Returns roadworks PLANNED on one motorway, one Bundes-/Landesstraße in NI, BW, MV, SN or TH (BY: B only), or city streets by place, in a date window: section, restriction, dates. Use when a date or window is named, it says geplant, or how long a site lasts ("Baustellen auf der A7 in den Sommerferien?"). ONE road/place per call. Do NOT use when more than one motorway is named, for the situation this minute, or for Baustellen with neither date nor geplant — all three are check_autobahn_traffic; whether a road is open — check_road_status. ≤ 92 days, max 20 sites. Show attribution. |
find_sharingread-only | Returns rentable shared bikes near a place or coordinate: bike-sharing stations with bikes and free docks now, and free-floating bikes around, with distance and data age (nextbike incl. KVB Rad, MyRadl, VAG_Rad; Donkey Republic). Use when someone asks for a rental or shared bike ("Leihrad", "Fahrradverleih", "nächstes nextbike", "bike share near me"). Do NOT use for parking (find_parking) or a general look around a place (find_nearby). Radius ≤ 5 km, ≤ 20 stations; e-scooters are not covered. Shows each source's attribution. |
get_departuresread-only | Scheduled departures from any German stop — bus, tram, U-Bahn, S-Bahn, train, ferry. Use when asked when a bus, tram, U-/Stadtbahn or ferry goes ("welche Bahnen" at a Hbf too), or for another DAY or a time over 2 h away: "Wann fährt der nächste Bus ab Fulda Bahnhof?" Do NOT use for a railway station's trains now or later today — get_train_departures. Plan times, with a live delay or cancellation per row where held; regional punctuality check_transit_disruption. No A-to-B journeys: say so, no call. Holds ≥ 48 h ahead, ≤ 3 days; further out, say so. 15 per call. Show the attribution line. |
get_driving_rulesread-only | Returns the German road rules a visitor needs: low-emission zones (Umweltzone) and the Feinstaubplakette, speed limits (advisory 130), winter tyres, alcohol, the Sunday lorry ban, tolls, Rettungsgasse, what must be in the car, electric cars. Use when someone drives through Germany or asks whether they may enter a city or street. Do NOT use for live traffic or closures: check_autobahn_traffic; to FIND a charger: find_charging_station. city narrows to its zone; place or lat+lon checks a point against the published zone boundaries. Sourced, dated; show the attribution. Not legal advice. |
get_train_departuresread-only | Next trains from a German railway station: platform, delay, cancellations. Use when asked when a train, S-Bahn or ICE leaves a named station, or if a train or line from it is late ("RE1 from Köln Hbf late?"); later today ("heute Abend") stays here. A line with no DEPARTURE station ("ist die S1 pünktlich?"; a destination, "nach …"/"zum …", is not one) — check_transit_disruption. Do NOT use for buses, trams, a non-railway stop, another day or a time over 2 h away — get_departures. Train type: categories (ICE/IC/RE/RB/S); no destination filter. ≤ 15 rows, ≤ 120 min. Show the attribution line. |
stop_watch | Ends a watch this conversation opened with watch_situation, so no further notifications arrive for it. Use when the person no longer needs to be told — "du musst mir nichts mehr zur A8 sagen", "stop watching that charger". No id at hand: pass kind ("weather") and key in the person's words ("A8", "Bamberg", "Kiel"); one match is stopped, several are listed. Do NOT use to look a situation up (call check_road_status), to list what is running (read viafrei://watches), or to cancel anything outside this chat. Another session's watch is never found. Results carry their attribution line. |
watch_situation | Opens a watch so THIS conversation is told when something changes: a road reopening, a stop running late, a weather warning, a charge point turning free. Use when asked to be told later: "sag mir Bescheid, wenn die A8 wieder frei ist", "tell me when a warning comes for Kiel". A name is enough as the key; no lookup first. Do NOT use to look up now, nor for e-mail, SMS or any alert outside this chat — we cannot send one; say so. Set hours (≤ 24, default 3) to cover the time asked about; condition narrows it (only the reopening, one charge point). Session-scoped, ≤ 10 watches. Show attribution. |
