Services and Solutions: Query / Response Data

Sometimes known as an XML or Javascript solution, the Query / Response server can be used to receive real-time, delayed, or end-of-day snapshot prices when requested, rather than pull continuous streams of data, as in a broadcast feed. Most website applications are suitable for Query / Response data setups.

The ddf database is one of the most pristine databases in the industry. With enhanced error-checking capabilities, our data files can provide your service with quality data from all of our data sources.

Query/Response data is priced by usage on a calender basis.
