The Country API returns basic information on all of the countries in the world. Available information includes the country's name, native name, native language, numeric code, alpha 2 code, alpha 3 code, region, sub-region, latitude, longitude, area, currency name, currency code, currency symbol, and flag. This API is completely free and open-source and doesn't require any form of authentication. The service is always available, and there are no request limits.
