  title: Country.io Data API
  description: >-
    Country.io publishes a small set of static JSON files that map ISO 3166-1
    alpha-2 country codes to common reference data (country names, capital
    cities, continent codes, ISO 3166-1 alpha-3 codes, telephone dialing
    codes, and currency codes). Each endpoint returns a flat JSON object
    keyed by the two-letter country code.
