Google/Yahoo alternatives to geocoding?

Question

Does anyone know of a good and accurate alternative web API for geocoding an address that is not Google or Yahoo?

I want to input an address/city/state/zip and have it return to me the latitude and longitude.

Ideally, I would involve it via a simple HTTP GET, e.g.

http://example.com/?location=123 Main St, New York, NY

and it would return JSON or XML with the latitude or longitude information.
