Searching on Eventful can be as simple as What, Where, and When, but sometimes you might want to find something more specific or weed out results that aren't relevant to your application.
Eventful has millions of events available as high-quality XML data feeds. Each feed can be customized by location, category, performer, or other criteria. Results can be accessed on-demand via the Eventful API or in compressed data files delivered on a regular schedule.
