In what country are the coordinates 41.44241, 21.31530 ?

A manual Google Maps search tells me it is in Macedonia.

Is there a program (or library) that would tell me this programmatically?

Requirements:

• If the coordinates are not in a country, it should say sea or something appropriate
• For contested areas like Kashmir, anything is fine, I am not picky
• Free
• Works on Linux
• If no library/program is available, a web API can be OK too but it must accept at least 50,000 requests daily
