🟢list_origins
Returns the departure airports (IATA) that have at least one priced weekend calendar, with the count of priced destinations per origin. Start here to learn what cheapest_weekends can answer at once. weekend_prices works for any airport pair and searches live when needed.
Input Schema
{
"type": "object",
"properties": {},
"additionalProperties": false
}🟢weekend_prices(origin, dest, currency, combo, cabin, ...)
The next 47 weekends (328 days) for one origin-destination pair, with the cheapest round-trip price per weekend and the time the price was observed ("as_of"). Cached prices answer at once; weekends not priced yet are searched live during the call, the way a page visit searches them (usually 10-40 s, at most ~55 s). If the search does not finish, the answer says which weekends are still open and to call again. Takes every filter the route page has: weekend shape (combo), cabin, stops, passengers, departure and return time windows, currency. Free: fri-sun, economy, any stops, any passenger mix, no time window. Pro session cookie: other combos, other cabins, time windows.

}🟢cheapest_weekends(origin, month, limit, currency, combo, ...)
The cheapest weekends from one origin across every destination that has a calendar under these filters, sorted by price. Optional month filter (yyyy-mm). Takes the same filters as weekend_prices. This tool reads what is already priced; it does not search every destination. A destination that is absent can be priced with one weekend_prices call for that pair. Pro only: this tool is Anywhere (every destination from one origin). Without Pro it answers pro_required with the Anywhere page url. One route at a time is free with weekend_prices.
