# AutoComplete Control: Proxyless AutoComplete pointing to the Yahoo! Search API

This AutoComplete instance uses a Script Node type of DataSource in order to retrieve data from a cross-domain server, Yahoo!'s Audio Search API, without the need for a proxy. The webservice must support a "callback" parameter, which the AutoComplete widget will use to pass in its internal callback function. The DataSource schema is defined to parse the return data for fields named "Name" and "Thumbnail" (in order to display a thumbnail image to the user).
