Options for simple geolocation feature?

Question

I need to add location features to a classifieds app. Basically,

• Users must search for classifieds by city and state
• Results should include nearby city and states (e.g. results within 50 miles)

I am clueless about the APIs I could use, if any. Any help would be appreciated. Thank you.
