Checking Stock from remote site using xml or soap

I have a shopping cart that displays items from a particular vendor. What I want to do is check stock availablity via XML/soap request when the user clicks on the details button of the product.

Two questions...

Does nopcommerce support this, meaning is there a soap or xml interface that I can call?

If so, where would be the best place to call this function?

I realize I will have to recompile application.

Thanks in advance!

You can call the external web service from Nopcommerce, you need to customize the code in order to do this, I suggest you get familiarized first with the Product service in the NopCommerce library to see the best way to implement it.
