I'm looking for a database for accessing the product information which are available in India. The list of UPC's and ISBN's or all the information of a product.
For the ISBN's, you may find interest in Worldcat. It allows searching with ISBN codes, and by language. Hindi is one of the searchable languages. They also offer an API, but to perform unrestricted search requests you have to be affiliated to a Library, otherwise it's free. The other alternative is also to write your own API that scraps the results off web pages.
As for the UPC codes, there is the UPC database that has millions of items (though, not sure how many Indian UPC codes there are). Otherwise you can also use the Google Search API for Shopping, which is deprecated, but offered until September 2013. To search by UPC codes, you have to use the
gtin parameter in the URL.
If you are interested, read this article about the GTIN - Global Trade Item Number, which explains how it is related to UPC. If you are not, I'll make it short, the GTIN-12 format is UPC.
If you're a Flipkart Affiliate, you can access their Product (and Offers) feed. The products have a custom Flipkart Id and not something general that you can compare with elsewhere.
Checkout Amazon's affiliate program. Their API includes products (lookup by UPC or EAN) from various countries throughout the world. https://affiliate-program.amazon.com
I think u could use some api to help you in your project.
UPC and ISBN, We can call them Gtin code. It could be 8, 12, 13 or 14 digits long.
You could use this database: https://market.mashape.com/mignify/gtin2product
It's an easy use API, U can use it to get directly the product information by gtin. Also It could help u to extract the information of a page from E-commerce site. It allows you to search by EAN, UPC or ISBN, even with language variations.
Hope it could help U.
