World Cities: Autocomplete by Prefix
geomelonautocomplete/autocomplete-place
Returns up to 10 cities in the chosen country whose name starts with the prefix, largest first, with the name in the chosen language and an English name when it differs. Each city carries its id, name, population and flag emoji. A prefix with no match, or a country and language pair the service does not hold, is refused as a validation error rather than returned as an empty list. City data from the Geomelon city autocomplete API. Passed through unmodified and served by Eden Engine; not an official Geomelon product.
