Local Calling Guide

XML query interface

This site offers XML output for certain queries. Use this instead of the web interface if you want to do automated lookups.

In general, output fields are the same as in the web interface. Since these queries may return large volumes of data you may wish to cache the results.

Other queries may become available in the future.
