FINN Auto - Car Subscription

Search available cars on FINN with filters. Returns matching vehicles with prices, images, and links. All filter values use German names (e.g. "Elektro" not "Electric", "Schwarz" not "Black"). IMPORTANT: Always show detail_url as a clickable link for each vehicle. The vehicle_id field is an internal API identifier for get_vehicle_details — never display it to users.

Get full specifications, equipment, all images, and pricing per term for a specific vehicle. Use a vehicle_id from search_vehicles results. IMPORTANT: Always show `detail_url` as a clickable link — it points to the FINN configurator where the user picks term and km. To produce a direct checkout link for a specific term + km combination (and optionally a one-time Fahrzeugbereitstellung), call `get_subscription_pricing` and use the `checkout_url` it returns. Never construct checkout URLs yourself. The `vehicle_id` field is an internal API identifier — never display it to users.

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.

Get canonical FINN URLs for a brand and its models — for building internal linking blocks on SEO pages. For each model returns three URLs that target DIFFERENT funnels: `mdp_url` (marketing/brand page), `plp_subscribe_url` (subscription product listing, /de-DE/subscribe/{brand}_{model}), and `plp_leasing_url` (leasing product listing, /de-DE/leasing/{brand}_{model}). Use `plp_leasing_url` when linking from a Leasing advisory, `plp_subscribe_url` when linking from subscription content. If `model` is omitted, returns all currently available models for the brand.
