Google has just released its API's to the general public.
"Google have released the first beta of their Web APIs package. Used in conjunction with a free license key this SOAP based web service allows developers to execute up to 1000 automated queries a day, but is currently available for non-commercial use only. The download comes with Java and .NET code examples and includes a WSDL description for use with other SOAP supporting languages."
