The endpoint is live and responds with a standard 402 Payment Required challenge, settling payments via the Tempo method on chain ID 4217 (Tempo L2) using pathUSD.\n\nEach call 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 request. The provider covers gas fees (feePayer: true), so callers only pay the data fee. Payment is one-shot per call (intent: charge).\n\nNo OpenAPI schema, documentation pages, or example responses were found on the provider's subdomain — all auxiliary routes return 404. The endpoint's functionality is inferred solely from its name, the MPP challenge metadata, and the parent GoFlightLabs description. The response likely contains a JSON array or object listing countries with codes, names, and possibly related aviation metadata, but this cannot be confirmed without documentation or a paid request.","tags":["flights","tracking","prices","airlines","airports"],"capabilities":["retrieve-countries","flight-data","aviation-reference-data","pay-per-call","micropayment-protocol","tempo-l2-settlement","pathusd-payment"],"categories":["geo","travel"],"synonyms":["country list API","aviation countries","flight labs countries","country codes API","GoFlightLabs countries","airline country data"],"warnings":["No OpenAPI schema or documentation available — all auxiliary routes return 404.","Response format is unknown; no example response could be captured.","Currency contract address 0x20c000000000000000000000b9537d11c60e8b50 assumed to be pathUSD with 6 decimals; if decimals differ, the stated price ($0.005) would be incorrect.","The root domain returns 404, suggesting minimal provider web presence."],"endpointUrl":"https://goflightlabs.mpp.tempo.xyz/retrieve-countries","protocol":"mpp","transport":"http","auth":{"type":"mpp","details":{"realm":"mpp.tempo.xyz","intent":"charge","method":"tempo","service_methods":{"tempo":{"assets":["0x20c000000000000000000000b9537d11c60e8b50"],"intents":["charge"]}}}},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is parseable, but there is zero documentation, no schema, no example responses, and all doc/auxiliary routes return 404.
