If you don't need a lot of zip / radius searches per day you can try the following:
http://www.truesitetools.com/zip_radius/ At the top of the page is a form to fill in and get back a list of Zips in a radius (not what you need). At the bottom of the page is what you were asking for, an API to call with a zip and radius, which will return a comma sep list of zips. I do have this running on a shared server, so if you need very many queries per day please don't use this. Perfect for an application with light needs to save themselves from setting up a zip code db table.
