SiteCheck

api.sitecheck-api.workers.dev · x402

Flight fares for one route and date, one-way or round trip: the cheapest, the fastest and the cheapest nonstop option, then up to 20 itineraries sorted by price with carrier, stops, duration, departure and arrival times (local and UTC), every flight segment and aircraft. Cabin, maximum stops and market (sets the currency) are optional. Fares for a single traveller from Ignav; a fare search, not a booking.

x402: an unpaid request gets a 402 with the price and pay-to wallet. The check never pays.
