Price scraping is the automated collection of publicly displayed product prices and related context from websites. A reliable price scraper does not store a number alone: it records the product, seller, currency, availability, promotion state, location or store context, source URL, and observation time. Price monitoring then compares valid observations over time and reports meaningful changes.
For authorized Amazon data collection, rotating residential proxies are usually the best starting point. Use sticky sessions when a worker must preserve a marketplace, delivery destination, cookies, variant, or seller-offer flow.
Walmart product data is useful because it changes constantly. Prices move, promotions appear and expire, Marketplace sellers compete for visibility, and local pickup or delivery availability can differ from one store to another.
To use proxies for web scraping, configure the proxy endpoint, authenticate, set timeouts, and validate the returned page. Rotate routes between independent jobs, and keep one sticky route during requests sharing cookies or server-side state. This minimal Python Requests example sends an HTTPS request through an authenticated HTTP proxy.
Websites block web scrapers by layering technical signals with behavioral signals so that no single fix clears every check on its own. According to Akamai's 2024 State of the Internet report, bots make up 42% of all web traffic, and roughly two-thirds of that traffic is malicious rather than legitimate (Akamai, 2024).
A mobile proxy routes your internet traffic through an IP address associated with a mobile network, typically over 4G or 5G, while a residential proxy routes traffic through an IP address associated with a residential ISP connection, making the request appear to come from a home internet connection.
For an AI agent that runs its own HTTP client or browser, a practical setup is Proxidize managed cloud residential proxies connected to the tool that opens the target website. This fits workloads that need a residential exit, geographic targeting, or controlled proxy sessions. Keep a sticky session for related browsing steps and validate the returned content before the agent uses it.
Rotating mobile proxies route requests through IP addresses assigned by cellular carriers. They can be useful when a scraping or testing workflow specifically needs a mobile-network identity, but the right provider depends on more than pool size. Short HTTP requests, persistent browser sessions, carrier targeting, and high-bandwidth collection all need different rotation and pricing models.
Residential proxy pricing is usually advertised as a rate per gigabyte. That number does not necessarily tell you what will leave your card. Minimum purchases, fixed allowances, monthly renewals, temporary discounts, and expiring traffic can all change the real cost.
To use a proxy with Playwright, pass a proxy object either when launching the browser or when creating a browser context. The object needs a proxy server and can also include an HTTP proxy username, password, and comma-separated bypass list.
