I am looking for a solid WebService API that will allow me to submit an http request with a pre-validated US Street/City?state/Zip Address and return COUNTY in xml or json about 200 times per work day. I am aware that Google, MapQuest & Bing do this however the response will go into an internal database, my use does not fit into their free Terms Of Service and I can not afford their large fee for my very small business. It looks like TigerWeb may do it? Is the data good enough? What might a request look like? Many thanks in advance.
