StableTravel FlightAware Canonical Airport Code Lookup

Use this endpoint when you need to resolve or canonicalize airport codes for airports in a specific geographic region, especially when integrating with FlightAware services that require canonical identifiers. Prefer this over IATA-only lookups when you need the official FlightAware canonical code for downstream flight tracking or historical flight queries.

• Missing required bounding box parameters (north, south, east, west) returns a 400 error
• Invalid or out-of-range latitude/longitude values cause a validation error
• No airports found within the specified bounding box returns an empty result
• Bounding box too large may hit result limits or timeout
• Authentication or payment failure returns a 402 or 401 error
