Czartery

Charter seats sold on the Polish market by Rainbow, Itaka and TUI, behind one server — each operator through its own consumer endpoint. Rainbow gives the destinations it flies to, with the nearest departure and lowest per-person price, and a day-by-day view of outbound flights to one destination. Itaka returns full itineraries — both legs with airports, times and carriers — with a direct booking link. TUI prices destinations for a stay length. Every price is in PLN; results are cached for five minutes.

Fetching tools share one envelope — source says where the data came from, fetchedAt says when, query echoes what you asked. Rainbow’s list key is flights, but each entry is a destination, not a single flight. Compact JSON in one text block, exactly how agents like it.
