**APIs profiled:** 1

The Cities Database API by AirLabs provides a global reference dataset of cities keyed to IATA metropolitan area codes, ISO country codes, and geographic coordinates. The API is consumed alongside the AirLabs Airports, Airlines, and Flights APIs to power travel search, mapping, geocoding, and clustering experiences. Authentication uses an api_key query parameter obtained from the AirLabs account dashboard. All responses are JSON arrays of city objects.
