But I think I miss part of the picture here, there is probably a channel transmitting structured information like this from manufacturers to vendors, I just never found it.
We have a standardized taxonomy and ontology to which we map all our products to. It's a garbage in garbage out problem but as long as the product has the information in some sort of semi-structured or unstructured form, we typically can infer attributes and standardize them based on their ontology (i.e. They have 4 USB ports)
I certainly won't add a credit card to a service that does nor show me pricing information.
Guys, I get that the enterprise market is comfortable and the usual target for this kind of thing, but if you don't want to bother with startups/developers, why do you market to them on your website and by answering here? You are completely unuseable like that. Hiding pricing information to sell overpriced services to big enterprices that just don't care is completely unacceptable for everyone else.
You can checkout Open Food Facts though the amount of data is sparse.

Disclaimer: I used to work for BDNA, and on this product, but have since left the company.
That said, I no longer work there, and companies often tinker with prices, and to boot, they were reengineering the API that I originally POCed for the company, so it could be substantially cheaper now (or substantially more expensive -- but the goal was to make it more accessible, so I'd guess cheaper.)
If you're actually interested in giving it a spin, shoot me an email, and I can probably put you in touch with someone willing to let you do a test-drive. My email's in my profile.
