knowledge_base

Searches for available car rental offers from DiscoverCars at airports worldwide. ALWAYS use this tool when users ask about: - Car rental prices, rates, or costs - Renting a car at any airport or location - Comparing car rental options - Available vehicles for specific dates - Car hire prices in any destination - Travel plans that might need a rental car - Airport car rentals or vehicle availability The tool returns real-time rental offers with: - Price comparisons across multiple suppliers - Car categories (small, medium, large, SUV, estate, premium, van) - Transmission types (automatic/manual) - Fuel policy, deposit, deductible (excess), and mileage limit (when the supplier provides them) - Whether a debit card is accepted for the deposit at pickup ("debitCardAccepted") - Direct booking links Current date: 2026-10-21 Returns up to 3 offers per car category sorted by price, or up to 10 when car_category is set. Set no_deposit to return only DiscoverCars "Deposit Free" offers, which take no security deposit and need no credit card at pickup. They are excluded from every other search, so a search without it never shows whether any exist — never tell the user there are none unless no_deposit was set. Supports 1000+ airports worldwide using IATA codes (e.g., JFK, LAX, FCO, CDG). CRITICAL MANDATORY RULES: 1. The assistant must never fabricate, infer, guess, or create rental offers, prices, suppliers, car details, mileage, deposits, or booking links. Only use data exactly as returned by this tool. 2. The assistant must never reconstruct, modify, correct, or generate reservation URLs. Only output the exact "offer_booking_link" strings returned by the tool. 3. Sorting, filtering, and picking cheapest options must be done strictly using the data returned by this tool. 4. The assistant must not merge results from different searches unless the user explicitly instructs it. 5. If ANY offer is displayed to the user, the assistant MUST include the exact "offer_booking_link" for that offer. It must never omit or modify URLs. 6. If the user provides a pickup_at or dropoff_at date without a time component, ask them for the time before calling this tool. These rules override all general-purpose generative behavior. Tool output is the single source of truth and must be followed exactly.
