Product Search Script needed for Price Comparison Website

I need a product search script for CJ, Linkshare, Google Affiliates, ShareaSale, other networks and advertisers. I maintain a price comparison website that runs behind an osCommerce store and uses data from affiliate networks and advertisers to provide "more buying options" for my OSC store customers. Currently we use csv data downloads from CJ and ShareASale, plus a script that queries [login to view URL]'s product search API. The [login to view URL] script is more efficient saving us time and disk space compared to CVS downloads from CJ, ShareaSale and other merchants/advertisers. Now I want scripts that will make API Calls to CJ, ShareaSale, Linkshare, other networks and advertisers similar to the [login to view URL] script. We would maintain a cache for performance reasons but we want to avoid storing large CSV/XML/RSS product data that becomes obsolete by the time it is loaded to our database. The requirement is pretty basic: Provide a script that makes web service calls - to query the available Product Search APIs: CJ: Product Catalog Search Service (REST) API LinkShare: Merchandiser Query (REST) API Google Affiliates: to be discussed ShareaSale: to be discussed eBay: to be discussed etc and present the results to the visitor. We already have [login to view URL] and you can use this as an example. Please see attached conceptual drawing.
