duffel_flight_search
ActiveTool of Duffel
declared in 0.1.0
Search flights (with pricing) from <origin> to <destination> on <date> — returns the 5 cheapest real, bookable offers from the Duffel Flights API, each with total price, airline, and per-segment flight numbers/times. Pass `return_date` for a round trip. This is REAL flight inventory: use a Duffel test token (duffel_test_...) for sandbox results. Example: duffel_flight_search({ origin: "JFK", destination: "LHR", departure_date: "2026-08-15", passengers: 2, cabin_class: "economy", _apiKey: "duffel_test_..." })
