Not exactly what you need but I think it may be close.

I’m running a SaaS turning affiliate platform content into an API which can be looked up by EAN13 : https://datafeedapi.com

Current users are publishers wanting to display affiliate links on their website but I could probably repurpose it for a more generic product search API without the affiliate links and different pricing. If anyone is interested, you can reach me at patrick_[at]_datafeedapi.com
