Tools

search_flightsSearch cheap flights between two airports or cities and return the cheapest all-in fare plus a cheapest-sensible alternative (penalises 20h+ layovers and risky overnight transfers). Compares Kiwi.com live fares with Duffel and Aviasales data, expands nearby airports and combines self-transfer one-ways when cheaper. Strong on Africa routes (Abidjan, Dakar, Lagos, Accra, Nairobi, Casablanca). One-way, return, multi-passenger, cabin and bag filters. Example: {"origin":"ABJ","destination":"CDG","departureDate":"2026-12-18","returnDate":"2027-01-05","flexDays":3,"currency":"XOF"}. Returns {cheapest, cheapestSensible, offers[], sources, notes}.
find_cheapest_datesCheapest known fare for each day of a month on one route: a price calendar to pick the cheapest day to fly. Example: {"origin":"DSS","destination":"LIS","month":"2026-12","currency":"EUR"}. Prices may be cached (priceKind indicative); confirm with search_flights before booking.
explore_cheap_destinationsWhere can I fly cheaply from here? Lists the cheapest destinations from an origin for a month, optionally under a budget. Example: {"origin":"ABJ","month":"2026-12","budget":400,"currency":"EUR"}.
get_flight_offerFull details of one offer from search_flights: legs, segments, layovers, baggage, fees and warnings. Example: {"id":"off_8f2c1a"}. Offers expire about 30 minutes after the search.
get_booking_linkTracked booking URL for an offer (Kiwi.com or Aviasales) plus self-transfer and cached-price warnings to show the traveller. Example: {"id":"off_8f2c1a"}.
list_flight_sourcesWhich flight data sources are live right now (Kiwi.com, Duffel, Aviasales) and cache status. No input.
unlock_mcpStart a one-time 2 EUR or 2 USD checkout (cards, Wave, MTN via lomi.; Stripe fallback) that removes the 5 searches/day preview limit. Pay in EUR, USD or the XOF (FCFA) equivalent. Example: {"email":"me@example.com","payCurrency":"EUR"}. Returns checkoutUrl; the lifetime token is issued only after the signed payment webhook.
