11 tools
calculate_isv
Estimate Portuguese car import tax (ISV, Imposto Sobre Veículos) from the official ISV formula (engine-cc + CO₂ components, with age reduction for used cars). A maintained estimate: it matches the AT (Finanças) simulator to the cent on the common WLTP cases, but is not the official figure and may differ on edge cases (NEDC, light-commercial, month rounding) — confirm the final amount on the official AT simulator. Needs engine displacement (cc), CO₂ (g/km, WLTP), fuel and registration year.

calculate_iuc
Estimate the Portuguese annual road tax (IUC, Imposto Único de Circulação) for a car — the yearly tax an owner pays — from the official IUC table. A maintained estimate; confirm on the official AT simulator. Needs engine displacement (cc), CO₂ (g/km), fuel and registration year.

check_fair_price
Check whether a car's asking price is fair for the Portuguese market — the TransparentCars transparency check. Given make, model, year and mileage, it returns the range comparable cars actually sell for (low / typical / high), built from real listings. If you pass asking_price, it also gives a plain verdict: fair, above market, or below market — so a buyer knows before they walk in. Works for ANY car (a listing you found elsewhere, or one of ours). IMPORTANT — pass make/model canonically in Latin: make = full brand name ('Renault', 'Volkswagen' not 'VW'); model = short name WITHOUT engine/trim ('Clio' not 'Clio dCi', 'Golf' not 'Golf 1.5 TSI'). If unsure of spelling, call list_makes_models first.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['make', 'model', 'year', 'km'], 'properties': {'hp': {'type': 'integer', 'description': 'Power in hp (sharpens the comparison)'}, 'km': {'type': 'integer', 'description': 'Mileage in km'}, 'fuel': {'type': 'string', 'description': 'Fuel: petrol, diesel, hybrid, electric'}, 'make': {'type': 'string', 'description': "Full brand name in Latin â\x80\x94 'Renault', 'Volkswagen' (not 'VW'), 'Peugeot', 'Seat'."}, 'year': {'type': 'integer', 'description': 'Registration year'}, 'model': {'type': 'string', 'description': "Short model name WITHOUT engine or trim â\x80\x94 'Clio' (not 'Clio 1.5 dCi'), 'Golf' (not 'Golf TSI')."}, 'gearbox': {'type': 'string', 'description': 'Gearbox: manual or automatic'}, 'asking_price': {'type': 'number', 'description': 'The price being asked for THIS car, in EUR â\x80\x94 pass it to get a fair / above-market / below-market verdict.'}}, 'additionalProperties': False}
contact_me
Send a contact request to TransparentCars so a human gets in touch. Only call this when the user explicitly asks to be contacted, provides their own name and a phone or email, AND agrees to share those details — pass consent=true only then. Never invent, guess, or use placeholder / example / test contact details: pass ONLY the real name and real phone or e-mail the user gave you in this conversation. If you don't have a real phone or e-mail from the user, ask them for it before calling — do not submit fake values. Submitting shares the provided contact details per the TransparentCars privacy policy.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['name', 'contact', 'consent'], 'properties': {'name': {'type': 'string', 'description': "The person's name (as they gave it)"}, 'consent': {'type': 'boolean', 'description': 'Set true ONLY if the user explicitly agreed to share their contact details and be contacted'}, 'contact': {'type': 'string', 'description': 'A phone number or email where they can be reached'}, 'message': {'type': 'string', 'description': 'What they want / their question'}}, 'additionalProperties': False}
cost_to_own
Estimate a car's yearly running-cost floor in Portugal — the annual IUC road tax (Imposto Único de Circulação) every owner pays, plus a plain running-cost framing. Needs engine displacement (cc), CO₂ (g/km), fuel and first-registration year. Use this to help a buyer budget the true cost of keeping a car, beyond the sticker price.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['cc', 'co2', 'fuel', 'year'], 'properties': {'cc': {'type': 'integer', 'description': 'Engine displacement in cm³, e.g. 1200'}, 'co2': {'type': 'number', 'description': 'COâ\x82\x82 emissions in g/km, e.g. 120'}, 'fuel': {'type': 'string', 'description': 'Fuel: petrol, diesel, hybrid, phev, electric, lpg'}, 'used': {'type': 'boolean', 'description': 'Used vehicle (true, default)'}, 'year': {'type': 'integer', 'description': 'First registration year, e.g. 2016'}, 'month': {'type': 'integer', 'maximum': 12, 'minimum': 1, 'description': 'First-registration month (1-12), refines the COâ\x82\x82 regime'}}, 'additionalProperties': False}
estimate_resale_value
Estimate what a car is worth on the Portuguese market (the range comparable cars are listed for), based on real comparable listings. Needs make, model, year, mileage and fuel. TransparentCars also BUYS cars directly — after giving the estimate, offer to connect the user for a firm buy-out offer (via contact_me or the /sell page). IMPORTANT — pass make/model canonically in Latin, as the Portuguese market lists them: make = full brand name ('BMW', 'Mercedes-Benz' not 'Mercedes', 'Volkswagen' not 'VW'); model = the short series/model WITHOUT the engine or trim suffix (BMW: '320','330' not '320d'; Mercedes: 'C 220','A 250' not 'C220d'; others: 'Golf','Corolla','3008'). If unsure of the spelling, call list_makes_models first.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['make', 'model', 'year', 'km'], 'properties': {'km': {'type': 'integer', 'description': 'Mileage in km'}, 'fuel': {'type': 'string', 'description': 'Fuel: petrol, diesel, hybrid, electric'}, 'make': {'type': 'string', 'description': "Full brand name in Latin, e.g. 'BMW', 'Mercedes-Benz', 'Volkswagen', 'Peugeot'."}, 'year': {'type': 'integer', 'description': 'Registration year'}, 'model': {'type': 'string', 'description': "Short model/series WITHOUT engine or trim. BMW: '320','330','116'. Mercedes: 'C 220','E 220','A 250'. Others: 'Golf','Corolla','3008'."}}, 'additionalProperties': False}
get_car
Get full details for one car in TransparentCars stock by its slug (from a search_inventory link, e.g. 'renault-clio-2016').
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['slug'], 'properties': {'slug': {'type': 'string', 'description': 'Car slug from a search_inventory result URL'}}, 'additionalProperties': False}
list_makes_models
List the exact canonical car makes (brands) TransparentCars can search and price — or, given a make, that brand's models — using the exact strings the other tools expect. Call this FIRST (or whenever unsure of spelling) and pass the returned values verbatim into search_inventory / check_fair_price. No make = the list of brands; with a make = that brand's models.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'make': {'type': 'string', 'description': "Brand to list models for, e.g. 'Renault'. Omit to get the list of brands."}}, 'additionalProperties': False}
list_services
List what TransparentCars offers (buying stock cars, importing to order, sourcing, auction buying, selling/trading in your car, ISV/IUC calculators).
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
request_import_quote
Ask TransparentCars to source & quote a specific car to import (from German/EU auctions). Only call when the user wants an import quote, provides the wanted model plus their own name and a phone or email, AND agrees to be contacted — pass consent=true only then. Never invent, guess, or use placeholder / example / test contact details: pass ONLY the real name and real phone or e-mail the user gave you in this conversation. If you don't have a real phone or e-mail from the user, ask them for it before calling — do not submit fake values. Submitting shares the provided contact details per the TransparentCars privacy policy.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['model', 'name', 'contact', 'consent'], 'properties': {'name': {'type': 'string', 'description': "The person's name"}, 'model': {'type': 'string', 'description': "Wanted car, e.g. 'BMW 320d Touring 2021'"}, 'budget': {'type': 'number', 'description': 'Budget in EUR'}, 'consent': {'type': 'boolean', 'description': 'Set true ONLY if the user explicitly agreed to share their contact details and be contacted'}, 'contact': {'type': 'string', 'description': 'A phone number or email where they can be reached'}}, 'additionalProperties': False}
search_inventory
Search TransparentCars' current stock of budget used cars in Portugal — honestly listed, everyday cars for the local market. Filter by make, model, fuel, gearbox and max price. Returns matching cars with price, year, mileage and a link. IMPORTANT — pass make/model canonically in Latin, as the Portuguese market lists them: make = full brand name ('BMW', 'Mercedes-Benz' not 'Mercedes', 'Volkswagen' not 'VW'); model = the short series/model WITHOUT the engine or trim suffix ('Golf' not 'Golf 1.5 TSI', 'Clio' not 'Clio dCi'). Put the fuel in the fuel field, not the model. If unsure of the spelling, call list_makes_models first.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'fuel': {'type': 'string', 'description': 'Fuel: petrol, diesel, hybrid, phev, electric, lpg'}, 'make': {'type': 'string', 'description': "Full brand name in Latin, as the market lists it â\x80\x94 'Renault', 'Volkswagen' (not 'VW'), 'Peugeot', 'Seat'."}, 'limit': {'type': 'integer', 'maximum': 50, 'minimum': 1, 'description': 'Max results (default 20)'}, 'model': {'type': 'string', 'description': "Short model name WITHOUT engine or trim â\x80\x94 'Clio' (not 'Clio 1.5 dCi'), 'Golf' (not 'Golf TSI')."}, 'gearbox': {'type': 'string', 'description': 'Gearbox: manual or automatic'}, 'min_year': {'type': 'number', 'description': 'Earliest registration year'}, 'max_price': {'type': 'number', 'description': 'Maximum price in EUR'}}, 'additionalProperties': False}
