Google Search SOAP / AJAX API
Google used to provide a SOAP based API that allowed programmatic access to Google search results. It has since been discontinued, however those that obtained keys prior to December 2006 can still use them.
If you need programmatic access to Google search results, and do not have a SOAP API key it is still available, just under the somewhat misleading title of “Google AJAX Search API”, and in a different format (JSON rather than SOAP/XML).
Google even provide code snippets for accessing it in Flash, Java, and PHP. For details see Google AJAX Search – Non-Javascript Environments.
