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.
The following is a list of sample source code snippets that matched your search term. Source code snippets are chunks of source code that were found out on the Web that you can cut and paste into your own source code. Whereas most of the sample source code we've curated for our directory is for consuming APIs, we occasionally find something interesting on the API provider side of things. If you know of some sample source code that would be of interest to the ProgrammableWeb community, we'd like to know about it.
