All Products in MarketPress: Gathering all the Products in One Place using Post indexer Plugin

Hello Team,

I want to be able to create a webservice that can retrieve products from my network Market Press.

I assume that Post Indexer will gather all the products (it is assumed that all products in marketpress are submitted as page post) and I can create a custom plugin/webservice that can retrieve these products details.

Kindly confirm if my assumption is correct.
