eBay Markdown Manager via API

Question

Using PHP5, how can I use the eBay API to set all my 2000+ eBay Store items on sale except for a specific set of 45 items?

I can't find a way to do this on eBay's website, and would prefer an API method so that I can simply exclude a specific brand from my query.
