Kiwi.com scraper API

Kiwi.com API for flight search, cheapest dates, and explore

The Kiwi.com API is built for fare monitoring, travel search features and destination research. The flight search returns itineraries with price, segments, carriers, layovers, baggage rules and a booking link, and it marks itineraries that combine separate tickets.

Search one-way flights, or add a return date for a return trip with an outbound and an inbound leg.

Filter by passengers, cabin, maximum stops, price band and airlines. Every filter is applied before the results come back.

Sort by quality, price or duration. A search returns up to 50 itineraries and has no pages.

Read the calendar price of every day in a window and the cheapest flight to every destination.

Failed and blocked requests are never charged.

Frequently asked questions

No. Scrappa is an independent service and is not affiliated with or endorsed by Kiwi.com. The Kiwi.com API returns structured JSON from public flight data through a Scrappa API key.

Every Scrappa account includes 500 free credits each month. After that, each request costs one credit. Failed requests are never charged.

Kiwi.com returns one result set of up to 50 itineraries for a search. There are no further pages, so Scrappa offers a limit and never relabels page 1.

The calendar shows a price for the date and party in economy. A flight search returns the offers you can book now. Use the calendar to pick a day and the search to see the real fares.

With a price band, an empty list means no offer within that band. Without one, it means no offers for that route and date. Both answers are free of charge.
