It is part of a broader FlightAPI suite offering real-time flight prices, tracking, and airport schedules covering 700+ airlines. The endpoint is accessed via a simple GET request with route parameters specifying origin and destination airports.\n\nPayment is handled through the MPP (Micropayment Protocol) using the Tempo method on chain ID 4217. Each call costs 2000 base units of pathUSD (6 decimals), which equates to $0.002 per request. The provider covers transaction fees (feePayer: true), so callers only pay the stated amount. Settlement goes to the recipient address on Tempo L2.\n\nNo OpenAPI schema or documentation pages were found on the endpoint's domain. The endpoint is confirmed live, returning a proper 402 Payment Required challenge. The URL pattern `/trackbyroute/:rest*` suggests route parameters are passed as path segments (likely origin and destination airport codes), but exact parameter format is undocumented in available materials.","tags":["flights","prices","tracking","airports","airlines"],"capabilities":["flight-tracking","route-lookup","airport-pair-search","real-time-data","pay-per-call","mpp-tempo"],"categories":["travel","geo"],"synonyms":["flight tracker","route flights","airport to airport flights","flight search","flight status between airports","track by route","airline route lookup"],"warnings":["No documentation or OpenAPI schema found — parameter format and response structure are unknown","Root domain returns 404; no docs, pricing, or README pages available","Currency contract address could not be independently verified; price assumed to be pathUSD with 6 decimals based on Tempo L2 conventions"],"endpointUrl":"https://flightapi.mpp.tempo.xyz/trackbyroute/:rest*","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"mpp.tempo.xyz","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid 402 MPP challenge, but no documentation, OpenAPI schema, or example responses are available.
