I’m looking for a service I can use to find ZIP codes within a certain radius of a given ZIP code. So, I would really like to be able to, say, POST or GET to a service, give it “68131” and “50” and get a string of ZIP Codes back.
I’ve been searching online, but the ones I have found have these usage warnings on them or are not for commercial use.
I know I can download census data and get code to do it myself, but I don’t want to do that.
Does anyone know a reliable and commercially usable ZIP code service I can use?
Thanks!
