Kiwi API
Kiwi.com's Tequila B2B platform is a documented REST API with instant self-serve keys for flight search. Booking and live-pricing endpoints require a commercial agreement and negotiated production keys. Auth is a static apikey header, and first-party SDKs are unmaintained.
Frequently asked questions
Kiwi scores D+ on Supergood's API Report Card. Kiwi.com's Tequila B2B platform is a documented REST API with instant self-serve keys for flight search. Booking and live-pricing endpoints require a commercial agreement and negotiated production keys. Auth is a static apikey header, and first-party SDKs are unmaintained.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Kiwi.com s.r.o. is a Brno, Czech Republic-headquartered online travel agency and flight booking platform founded in 2012 by Oliver Dlouhy and Jozef Kahan (originally launched as Skypicker and rebranded to Kiwi.com in 2016).
Vertical: Travel & Expense (more specifically: online travel agency / flight booking / virtual interlining / B2B travel API infrastructure). Consumer flight search and booking on web (kiwi.com plus localized country sites) and mobile (iOS, Android). 'Anywhere' inspirational search (search a date range without a fixed destination).
Mid as a global consumer OTA; mid-low as a B2B flight API. Kiwi.com is consistently ranked among the top-10 global flight OTAs by traffic and bookings, with a particularly strong footprint across CEE, Western Europe, LATAM and SE Asia.
Flight inventory metadata: routes, fares, fare classes, baggage rules, layover details, carrier codes (hundreds of low-cost and legacy carriers). Virtual-interlining itinerary graph: algorithmic combinations of non-interlined segments across separate tickets.
Founded 2012 (14 years old as of 2026) as Skypicker, rebranded to Kiwi.com in 2016 and majority-acquired by General Atlantic in March 2019.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Kiwi has partial MCP support. Kiwi.com runs an official hosted MCP server at mcp.kiwi.com with public connection instructions for Claude, ChatGPT, Cursor, and other clients. It exposes only a single flight search tool, and the instructions repository has not been updated in over a year.
Partially. MCP support for Kiwi exists but is incomplete, so what MCP clients like Claude, Cursor, and Codex can reach depends on what the available server covers.
