On December 5th, we stopped accepting new sign-ups for the Google SOAP Search API. This change does not impact current users of the SOAP Search API -- you can continue to execute queries, and we have no plans to turn off the service in the future.
While the product was Google's first API and inspired a lot of Google's current developer products, we are no longer devoting resources to increase the capacity of the service, instead focusing our efforts on the AJAX Search API. While the AJAX Search API does not provide server-side access to search results, it has a number of more powerful features, including access to Video, Maps, Blog Search, and News search results.
