The endpoint is hosted at aviationstack.mpp.tempo.xyz and uses the Tempo payment method (pathUSD on Tempo L2, chain ID 4217) to settle per-call charges.\n\nEach request costs 5,000 base units of pathUSD. Assuming pathUSD uses 6 decimals (consistent with other USD stablecoins), this translates to $0.005 (half a cent) per call. The intent is \"charge\", meaning each API call is a one-shot payment. The provider covers gas fees (feePayer: true), so callers only pay the data cost.\n\nNo documentation, OpenAPI schema, or usage examples were found on the provider's origin site — all non-endpoint paths return 404. The endpoint itself is confirmed live, returning a proper 402 Payment Required challenge on GET requests. Based on the AviationStack upstream API, the endpoint likely accepts query parameters such as airport IATA/ICAO codes, city, or country to filter results, but the exact parameter schema is not documented at this proxy.","tags":["flights","aviation","tracking","airports","airlines"],"capabilities":["airport-lookup","aviation-data","pay-per-call","mpp-tempo","pathusd-settlement","l2-micropayment"],"categories":["geo","travel","data"],"synonyms":["airport search","airport information","IATA code lookup","ICAO airport data","aviation API","flight data","airport database","AviationStack airports"],"warnings":["No documentation found — all paths on the provider origin return 404.","No OpenAPI or schema available; request/response formats must be inferred from upstream AviationStack API.","Currency address 0x20c0...8b50 assumed to be pathUSD with 6 decimals based on Tempo L2 convention; if different, the price calculation would change.","Exact supported query parameters are unknown for this proxy endpoint."],"endpointUrl":"https://aviationstack.mpp.tempo.xyz/v1/airports","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 with a valid 402 MPP challenge, but there is zero documentation, no OpenAPI schema, no examples, and all doc paths return 404.
