FAQ

Questions about get_subscription_pricing

What does the get_subscription_pricing tool do? +

Calculate exact monthly subscription price for a specific vehicle, term, and mileage combination. Returns base price, km add-on, total, and a canonical checkout URL. Checkout URL structure (always use the URL returned in checkout_url verbatim — do NOT construct your own): https://www.finn.com/de-DE/checkout/cart/{vehicleId}/{term}/{kmPackage} https://www.finn.com/de-DE/checkout/cart/{vehicleId}/{term}/{kmPackage}?downPaymentAmount={amount} The three positional path segments after /cart are vehicle id, term in months, and monthly km package — in that order. About down_payment_amount (Fahrzeugbereitstellung): - Fahrzeugbereitstellung is a one-time vehicle provisioning fee. - When down_payment_amount is provided, it is paid upfront as Einmalzahlung (one-time payment) and the URL includes ?downPaymentAmount={amount}. - When omitted, the same fee is spread across the term and absorbed into the monthly price; the URL has no query string. It is categorised as a Read tool in the FINN Auto - Car Subscription MCP Server, which means it retrieves data without modifying state.
