We just had another company upgrade their service for the Zip Code API. We always love to see how people are using it. This one is a large online car resale website. It let’s the buyer look within a radius of their zip code for available cars.

Try out the API entering a zip code and radius here.
Share how you are using the Zip Code API, even if it is for free. Hopefully it will give others some good ideas!
