Skip the marketing. QuantumProxies.io publishes a machine-readable site map, Markdown for every page, a free MCP server, and APIs billed from the same balance as your proxies.

• Site index for LLMs — /llms.txt — products, APIs and country pages. Full text: /llms-full.txt
• This page as Markdown — Append .md to any URL for a clean text version
• MCP server — Scrape, search, map and crawl through residential proxies
• Scraper & SERP APIs — Any page as Markdown or JSON; structured Google, Bing and DuckDuckGo results
• REST API — Generate proxies, check balance and manage orders
• Get an API key — Register, top up, then create a qp_live_ key in the dashboard
