Google Maps, GeoCoding, and Distance based on Zip Codes? - google zip code map

I have used, difficulties in finding information about a good API for my research of encryption and client websites.

I have to work around a way to zip codes based on a user find, sends the zip code. Ideally, I would be able to find addresses is the basis and starting point at a distance.

Finally, I would bind them to a Google Map.

Who you can download a free API that can solve for me?

Thanks in advance!
