Given an airport identifier (IATA, ICAO, or LID code) in the URL path parameter `:id`, it returns the canonical airport code along with its ICAO, IATA, and LID variants. This is useful for normalizing airport codes across different naming conventions before passing them to other flight or airport endpoints.\n\nThe endpoint is a simple GET request with no query parameters beyond the path parameter. It costs $0.002 per call, paid automatically via the MPP (Tempo) or x402 micropayment protocol — no API keys or subscriptions required. Payment settles in pathUSD on Tempo (chain ID 4217). The response is a JSON object containing `airport_code`, `code_icao`, `code_iata`, and `code_lid` fields.\n\nStableTravel proxies FlightAware's AeroAPI data. The full OpenAPI 3.1 spec is published at `/openapi.json` and interactive docs are at `/docs`. The endpoint is confirmed live — it returns a 402 MPP payment challenge to unauthenticated callers, which is the expected behavior for the MPP protocol.","tags":["amadeus","flightaware","flights","hotels","activities","transfers","travel"],"capabilities":["airport-code-normalization","icao-iata-lid-lookup","flightaware-aeroapi-proxy","pay-per-request","mpp-micropayment","x402-micropayment","no-auth-required"],"categories":["travel","geo","reference-data"],"synonyms":["airport code lookup","canonical airport code","IATA to ICAO","airport identifier resolver","FlightAware airport canonical","airport code converter","normalize airport code"],"warnings":["Example response is inferred from the OpenAPI schema, not from an actual API call.","The path parameter :id is documented in the OpenAPI spec as a static path segment '/api/flightaware/airports/id/canonical' — the actual endpoint uses a path parameter substitution pattern."],"endpointUrl":"https://stabletravel.dev/api/flightaware/airports/:id/canonical","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 response shape, clear pricing ($0.002/call), live 402 MPP challenge confirmed, and comprehensive guidance docs.
