Kiwi.com Price Graph API Documentation Get a price curve for return trips: one point per departure date with the matching return date for the stay length you choose. Prices are economy prices for the date and party. They are not the cheapest fare of a flight search. Use the curve to find the best departure day for a stay of 3 to 5 nights, then open the flight search.
