I just implemented the USPS APIs and they all require a street address in order to succeed, due to the need for disambiguation. What I really wanted was something like you describe, because I don't always have a street address so much as a general region. All the other API offerings are way too pricey for my purposes, or look scammy. I ended up scraping Wikipedia and making a generic spreadsheet instead.
