eBay API Usage Report

Excellent new feature for people who use eBay Web Services.  The just-released API Usage Report enables you to see what API calls you've made.

Before, you'd have to keep track of this yourself.  Now, this web form will show you exactly which calls you've made over any given period of time.  You can even look six months back and specify hour ranges.

A very useful service for affiliate developers who want insight into how the eBay API increases their results.
