It accepts a JSON body with `originDestinations`, `travelers`, and `sources` arrays, supporting complex itineraries including multi-city routing, cabin class mixing, date/time windows, connection point filtering, carrier restrictions, and pricing options like refundable-only or included-checked-bags-only fares. The GET variant of the same path handles simpler one-way/round-trip queries via URL parameters.\n\nPricing is $0.054 per call (fixed), settled via MPP on Tempo (chainId 4217) using pathUSD, or via x402. No API keys or accounts are required — payment serves as authentication. The endpoint is live, returning a 402 MPP challenge on unauthenticated requests. Responses include an array of flight offer objects with itinerary segments, pricing breakdowns, and dictionaries for carrier/aircraft lookups.\n\nStableTravel is part of a broader travel API suite by Merit Systems that also covers hotel search/booking, activities, airport transfers, reference data (airports, airlines, routes), real-time flight tracking via FlightAware AeroAPI, and Google Flights price comparison. The typical booking workflow is: search → price confirmation (`/api/flights/price`, $0.032) → book (`/api/flights/book`, $0.086). Full OpenAPI 3.1 schema is published at `/openapi.json`.","tags":["amadeus","flightaware","flights","hotels","activities","transfers","travel"],"capabilities":["flight-search","multi-city-itinerary","gds-inventory","amadeus-api","cabin-class-filter","carrier-restrictions","fare-rules","connection-point-filter","date-window-search","pay-per-request","mpp-tempo","x402"],"categories":["travel","search"],"synonyms":["flight search API","multi-city flights","Amadeus flight offers","GDS flight search","flight booking API","airline search","travel API","flight availability","round trip search","one-way flight search"],"warnings":["Response schema data items are loosely typed (items: {}) — actual Amadeus response structure is not fully specified in the OpenAPI spec","This listing covers the POST method specifically; the GET method on the same path handles simpler searches with query parameters"],"endpointUrl":"https://stabletravel.dev/api/flights/search","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"stabletravel.dev","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.920","qualityRationale":"Full OpenAPI 3.1 schema with detailed request/response types, clear pricing in USD, live 402 MPP challenge confirmed, comprehensive documentation with parameter descriptions, examples, and workflow guidance.
