The last few months I maintain a github repository with resources for building travel applications. You can find information in json format for countries, maps, languages, phone codes etc. Also I wrote a small nodejs rest api that you install in your server if you want to have an endpoint to request countries info. And at last you will find a huge list of travel api links. Most of them are free! Below is a copy of the list as of today. Keep an eye on the repository for the latest version.
