api use
can I publish it to github and send to friends and family

My advice is DON'T DO THIS.
Your API Key is like a password.
If you publish or distribute it, it could be used by third parties, violating the Terms of Use.

By the way, I just read this exact same advice on Github.
A WARNING about passwords and API keys.
