AutoIsto CZ

Use this when the user asks for more about one specific car returned by search_cars (engine power, body, colour, price history, how long it has been listed). Requires the car id from search_cars; do not guess ids. Returns technical data and the AutoIsto price verdict; it does not return the seller's name, phone, description, VIN or licence plate — for contact the user opens the car's url. If the car is no longer in the offer, found is false.

Use this when the user asks how much a car model of a given year costs in the Czech Republic, or whether a price for it is reasonable. Returns, for one brand, model and model year: the median ASKING price in AutoIsto's current offer (any mileage) and the median LAST price at which such cars left the offer, each with its sample size, and the month. A figure is omitted when its sample is too small. Asking prices are what sellers ask, not sale prices, and a car leaving the offer is not proof of a sale; mileage and equipment move the price, so present it as a guide. Requires a year; if the user did not give one, ask. Do not use it for valuing a specific car's condition, for new-car prices or for markets outside the Czech Republic.

Use this when the user wants to find a used car for sale in the Czech Republic — by brand, model, body type, fuel, gearbox, year, price, mileage, power, number of seats or town/region. Covers listings sellers published on AutoIsto directly and public listings from Czech car portals. Pass the criteria as ONE short phrase in Czech (Slovak also works), with numbers as the user said them and prices in CZK. Examples that are fully understood: "škoda octavia kombi nafta automat od 2017 do 350000 Kč", "suv automat do 600000 Kč", "bmw x5 diesel od 2019 do 1000000 Kč", "kombi do 250000 Kč Brno", "9 místná dodávka". Use at most ONE body type per call (kombi, SUV, sedan, hatchback, liftback, MPV, kupé, kabriolet, dodávka, pick-up); for two body types make two calls. Leave out filler and wishes that are not filters (auto, do města, spolehlivé) and equipment (tažné, panorama) — unknown words are not applied and are listed in notUnderstood. Returns up to 10 cars with price verdicts, what was understood, which criteria were relaxed when nothing matched exactly, which words were not applied, and a link to all results. Limits: only cars currently listed on AutoIsto (Czech Republic, prices in CZK); no new-car configurators, rentals, leasing offers or cars abroad; the offer changes daily, so a car may already be sold. Seat counts of 6+ are estimated from the model.
