Routing traffic/API calls through user with Python app rather then server

I'm working with an app that does various API calls to sites such as eBay, Amazon, Best buy, etc, I was wonder if it's possible to send that traffic from the users devices, so those services sees it as something that the user is requesting rather then a server with slot of users requesting it. Is something like that even possible with Python or any other language? Also, what about instead of using API, we just directly scrape the sites in questions using the users' devices and maybe process it on the server. Just want to avoid a lot of traffic being send from a single server, and spread it across the users if possible. - Thanks.
