The company for which I work is using CJ on one of it's sites, but the products and links are all hand edited. The owner is interested in using their API, but even reading about it on their website, it's not clear to me what all is possible with this set of web services. Does anyone have experience with it?

I get the idea of what a product or link search is but what I'm unclear on is just what type of searches are likely to be beneficial to us. What criteria should be included in a search and what criteria should I look at once I get the result? How does this data relate to the HTML that I present to a visitor?

If someone has a site using the API and wouldn't mind sharing a link, it might help me wrap my head around just what the API is capable of.

We'll probably be using PHP and REST.
Thanks.
