Tools · 3
find_cheapest_fareReturns the cheapest observed one-way fare between two cities, plus the six-month low and the departure date on which the low was observed. Use whenever the user names an origin and a destination and asks about price, the cheapest date to fly, or whether a fare is a good deal. Bolist_routes_fromReturns destinations reachable from one origin, sorted cheapest first. Use when the user asks where they can fly cheaply from a city, or wants inspiration rather than one specific pair. One call replaces dozens of page fetches. Prices are cached snapshots.resolve_cityTurns a spoken city name into the uppercase IATA city code the other tools expect. Call this before find_cheapest_fare whenever you are not certain of a code. Do not invent codes.Recent checks
