In what country are the coordinates `41.44241, 21.31530` ?

A [manual Google Maps search][1] 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
