Use curl's -H or --header option to send a Hypertext Transfer Protocol (HTTP) request header. Repeat the option for multiple fields, and use --json for JavaScript Object Notation (JSON) bodies. Inspect traffic with -v, -i, -I, or -D, keep credentials out of saved commands, and review custom fields before redirects.
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.
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).
The best proxy for an AI agent is Proxidize when the agent already has an HTTP client or browser and needs direct, auditable control of the proxy layer. Choose Bright Data when the agent should call one managed platform for search, scrape, crawl, extraction, and browser actions. Choose Decodo for a lower-cost managed scraping MCP, Oxylabs for enterprise Playwright sessions, ScraperAPI for simple fetch requests, Browserless for browser-first automation, Apify for reusable Actors, or Firecrawl for LLM-ready web content.
The best rotating mobile proxy provider depends on what you are actually buying. For a shared 4G/5G pool billed by traffic, Mobile proxies from Proxidize combines a flat $2/GB rate with city, ASN, and IP provider targeting in the US, UK, Canada, India, and Germany. It also offers an official Model Context Protocol (MCP) server that lets compatible AI clients help rotate IPs, switch locations, check usage, and manage access points. DataImpulse is the easiest low-cost global starting point, Decodo offers a strong mid-market feature set, and Bright Data provides the broadest enterprise control surface. IPRoyal publishes the longest configurable pooled-session duration, while SOAX has the clearest native UDP and QUIC support. There is no honest universal winner. A traffic-priced gateway into a shared mobile pool and a monthly dedicated mobile connection have different capacity, location, rotation, and session characteristics. Putting them in one price column without explaining those differences creates a misleading ranking.
Residential proxy providers use different pricing models, bandwidth commitments, and billing policies, making it difficult to compare plans on equal terms. A provider with a lower cost per GB may require a larger upfront commitment, while another with a higher advertised price may include features, volume discounts, or billing benefits that reduce your overall 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.
Most residential proxy providers promise massive IP pools, global coverage, fast speeds, and high success rates, making it hard to understand what actually matters.
