It is part of StableTravel's FlightAware history API suite, which proxies FlightAware AeroAPI data through a pay-per-request micropayment model. The response includes origin/destination airports (with ICAO/IATA codes, city, timezone), scheduled and actual gate/runway times, delays, aircraft type, route distance, filed altitude/airspeed, baggage claim, gate/terminal info, and flight status.\n\nThe endpoint costs $0.40 per request, settled via MPP (Tempo method on chain 4217) or x402 using USDC. No API keys or subscriptions are required — payment serves as authentication. The registration is passed as a path parameter (e.g., `/api/flightaware/history/aircraft/N12345/last-flight`). The endpoint accepts GET requests and returns a single flight object (not an array). This is one of the more expensive endpoints in the StableTravel suite, reflecting the underlying FlightAware AeroAPI cost for aircraft-level historical lookups.\n\nStableTravel is operated by Merit Systems and provides a full OpenAPI 3.1 spec at `/openapi.json`. The MPP challenge was confirmed live, returning a 402 with a valid payment challenge.","tags":["amadeus","flightaware","flights","hotels","activities","transfers","travel"],"capabilities":["aircraft-last-flight-lookup","flight-history","flightaware-aeroapi-proxy","pay-per-request","mpp-tempo-settlement","x402-settlement","no-auth-required","registration-based-query"],"categories":["travel","aviation","data"],"synonyms":["aircraft last flight","tail number lookup","plane registration history","FlightAware last flight","aircraft flight history","N-number last flight","tail registration flight data","aircraft tracking history"],"warnings":["Example response is synthetic — no actual paid response was captured in the probe","This is one of the more expensive endpoints at $0.40 per call"],"endpointUrl":"https://stabletravel.dev/api/flightaware/history/aircraft/:registration/last-flight","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"stabletravel.dev","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.880","qualityRationale":"Full OpenAPI 3.1 schema with detailed response types, clear pricing ($0.40/request), live MPP 402 challenge confirmed, and comprehensive documentation.
