If you simply want to have your results returned as XML exclusively, please reference this FAQ.

This FAQ is for users who wish to have their results returned as pre-formatted HTML, as specified via the 'Customization' options (Bronze customers) or via custom search templates (Silver & Gold customers), when a search is conducted from one location on their site, but may need also need to have the option to receive XML data from the FusionBot engine as well.

Is this scenario, DO NOT select XML as the default output option for your results, as specified in the following FAQ. Rather, customize your search results as you typically would, using the formatting options available within your package. This will ensure that your standard search results are returned as formatted HTML output. Then, when you wish to override the default value for returning your results as formatted HTML, pass an additional value, xml=keycode in the querystring that is submitted to the FusionBot engine.

Keycode is a unique four character alphanumeric value that is assigned to your account, in order to keep your search activity reports secure, preventing others from being able to view your search activity reports. To retrieve the keycode value assigned to your account, click on the 'Account' tab within your FusionBot account, and your keycode value will be listed on this page. If at any time you change your package level, a new keycode will be generated, and in order to keep your XML call functional, you will need to update this value in your call.

Therefore, if your assigned keycode value retrieved from the 'Account / Overview' tab were a2b3, you would need to construct your XML call as follows, in order to retrieve XML, rather than the default HTML output for your account:
