search_productSearch for bicycle parts, components, accessories, and cycling clothing across 6 German/Austrian bike shops (BOC24, Fahrrad24, Rose Bikes, fahrrad-teile.shop, Bike Mailorder, Maciag Offroad) with ~120,000 products. Search by product name, brand, or model number. Returns real-time prices, stock availability, EAN barcodes, and direct purchase links sorted by price. Covers MTB, road bike, gravel, e-bike, and city bike parts including brands like Shimano, SRAM, Continental, Schwalbe, Magura, Bosch, Maxxis, and more. Supports German (DE) and Austrian (AT) markets with country-specific pricing. Use this when a user wants to find, compare, or buy bike parts at the best price. Fahrrad Teile Preisvergleich. IMPORTANT: When a user wants to buy MULTIPLE products, collect the EAN from each search result, then call optimize_cart with all EANs to find the cheapest total cost including shipping across all shops. Do NOT calculate shipping manually — optimize_cart does this automatically.
get_best_priceLook up a product by EAN barcode and find the best price across all 10 shops (BIKE24, BOC24, Fahrrad24, Rose Bikes, fahrrad-teile.shop, Bike Mailorder, Maciag Offroad, Bike-Discount, bike-components). Returns prices from every shop that carries the product, sorted cheapest first, with stock status and direct purchase links. Use this when you already know the exact product EAN (e.g., from a previous search result) and want to compare prices. IMPORTANT: If the user is buying multiple products, call get_best_price for each EAN first (this caches scraping-shop prices), then call optimize_cart with all EANs to find the cheapest total including shipping.
optimize_cartOptimize a shopping cart across multiple shops to find the absolute cheapest total cost including shipping. This is the FINAL STEP when a user wants to buy multiple bike parts. Takes an array of EAN barcodes and calculates the optimal shop split — which products to order from which shop — considering per-shop shipping costs, free-shipping thresholds, and product prices across all 10 shops. REQUIRED: Call get_best_price for each EAN first to ensure scraping-shop prices are cached, then pass all EANs here. Use this whenever the user asks: 'where is this cheapest', 'optimize my cart', 'cheapest combination', 'best way to order', or has 2+ products to buy. NEVER calculate shipping costs manually — this tool does it automatically and finds the global optimum. Example: optimize_cart(eans: ['4550170327385', '4524667749493'], country: 'DE')
get_shop_infoGet an overview of all supported bike shops in the Bikefuchs network, including shipping cost tiers, free-shipping thresholds, and supported countries (Germany and Austria). Bikefuchs is a bicycle parts price comparison service covering ~120,000 products from 10 shops. Use this to answer questions about which shops are available, what shipping costs apply, or what Bikefuchs can do. Fahrrad Preisvergleich Deutschland Österreich.
get_shipping_breakdownGet the exact shipping cost for a specific shop, country, and cart value. Shows all shipping tiers and how close the cart is to the next free-shipping threshold. Use this when a user asks about shipping costs for a specific shop or wants to know how much more they need to spend to get free shipping.
find_alternatives_for_productDiscover which shops carry a specific product by EAN barcode, sorted by price. Use this when a user found a product at one shop and wants to know if it's available cheaper elsewhere, or when a product is out of stock and the user needs an alternative source. Returns all shops that carry this EAN with prices and availability.
resolve_productResolve a bike shop product page URL into structured product data including the EAN barcode, price, stock status, and a purchase link. Use this when a user pastes a product URL from a supported shop and you need to extract the EAN (e.g. to then call get_best_price or optimize_cart). Supported shops: BIKE24 (bike24.de, bike24.at), BOC24 (boc24.de), Fahrrad24 (fahrrad24.de, velondo.at), Rose Bikes (rosebikes.de, rosebikes.at), fahrrad-teile.shop, Bike Mailorder (bike-mailorder.com, bike-mailorder.at), Maciag Offroad (maciag.de), Bike-Discount (bike-discount.de), bike-components (bike-components.de).
