Search Products via API or Web Crawler

Navigation
4

I want to develop software that displays product information. I would like to know if the great ecommerce used here in Brazil (American, Walmart, Submarine, Extra) provide some API to look for the information of its products.

Another doubt. Would it be wrong for me to develop a robot (web crawler, spider, etc.) to get this information? For example, software that accesses the Americanas website, enter a certain product, get the information I need and store it in my database? Let's say that when I display the information I got from Americanas, I link to their site containing the product. This is perhaps even good for them.

The only API I found to search for products in Brazil was the one from Buscapé, which you can access here .

The APIs of other companies focus on the Marketplace and the products that can be listed are only those that the user registered via API.

If you are going to use some API and under the terms of use, or the documentation is clear that it is prohibited then it is not allowed to create.

B2W API (American, Submarine, Shoptime) here .

API CNova (Extra, Bahia Homes, Cold Point, Cdiscount, Barateriro and Deparu Viagens) here . p>

Have you browsed the 99apis ? I think there is the best place to find any API. In fact, there's B2W and CNova , which are what you are looking for, as our colleague @ adelmo00 spoke in his reply.

It's the hint for anyone looking for other APIs out there.
