Kiwi.com Tequila API
Famous for "Virtual Interlining" — combining flights from airlines that don't cooperate to create unique, ultra-cheap multi-leg routes. Tequila is Kiwi's developer platform for building innovative low-cost flight search tools.
What is Kiwi.com / Tequila?
Kiwi.com (formerly Skypicker) is a Czech travel technology company renowned for its "Virtual Interlining" technology — an algorithm that combines flights from different airlines that don't have interline agreements to create seamless multi-leg journeys at prices far lower than traditional through-ticketing. For example, a passenger flying Delhi to New York might be routed on IndiGo to Dubai, then on a budget carrier to Amsterdam, then on a third carrier to New York — all booked as separate tickets but coordinated to minimise layover risk.
Tequila is Kiwi's affiliate and API platform for travel developers and content publishers. It provides access to Kiwi's flight data, virtual interlining routing, and booking engine through a REST API. Partners earn a commission on bookings generated through their integration.
This API is particularly valuable for travel hackers, budget travel blogs, and price comparison tools targeting backpackers and cost-conscious travellers. The ability to surface routes that no traditional OTA or GDS would find makes Kiwi a unique value proposition for discovery-driven travel products.
Key Features
The core Kiwi differentiator — combines non-partner airlines into optimised multi-leg journeys. Creates routes impossible to find on any single airline or traditional OTA.
Search by route, flexible date ranges, maximum stopovers, airline type (LCC only, full-service, or all), and price limits. Returns results sorted by price.
Unique "nomad" search — given a list of destinations, find the cheapest order to visit them all. Ideal for travel bloggers and round-the-world trip planning tools.
When booking virtual interlining itineraries, Kiwi provides a "booking guarantee" — if one leg is missed due to delay, Kiwi rebooks the customer on an alternative flight at no cost.
Search across entire months or date ranges to find the absolute cheapest departure date. Essential for travel flexibility widgets and date-grid displays.
Airport, city, region and country autocomplete and lookup. Supports IATA codes, city names, and geographic bounding box queries for building smart search inputs.
