🟢search_cars(query)
Use this when the user wants to find a used car for sale in Slovakia — by brand, model, body type, fuel, gearbox, year, price, mileage, power or town/district. Covers listings sellers published on AutoIsto directly and public listings from Slovak car portals. Pass the criteria as ONE short phrase in Slovak (Czech also works), with numbers as the user said them. Examples that are fully understood: "škoda octavia kombi diesel automat od 2017 do 15000 €", "suv automat do 25000 €", "bmw x5 diesel od 2019 do 40000 €", "kombi do 10000 € Žilina". Use at most ONE body type per call (kombi, SUV, sedan, hatchback, liftback, van, kupé, kabriolet, dodávka); for two body types make two calls. Leave out filler and wishes that are not filters (rodinné, auto, do mesta, spoľahlivé) and equipment (ťažné, panoráma) — 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 (Slovakia, prices in EUR); no new-car configurators, rentals, leasing offers or cars abroad; the offer changes daily, so a car may already be sold.

}🟢get_car_details(carId)
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.

}🟢get_model_price(brand, model, year)
Use this when the user asks how much a car model costs in Slovakia, or whether a price for a model is reasonable. Returns the median ASKING price of the brand/model (optionally one model year) in AutoIsto's current offer, the sample size, the price range and the date. The median is omitted below 20 cars with a plain price. These are prices sellers ask, not sale prices; mileage and equipment move the price, so present it as a guide. Do not use it for valuing a specific car's condition, for new-car prices or for markets outside Slovakia.
