Residential from $0.80/GB · rotating or sticky · MCP server included
AI agents get blocked for a simple reason: they browse from datacenter IP ranges, reuse one address for hundreds of tool calls and carry no geographic context. Quantum Proxies gives an agent real residential IPs in 200+ countries, rotating or sticky sessions over HTTP or SOCKS5, per-GB pricing from $0.80 per GB, and an MCP server that hands Claude or Cursor live web access with the proxies already built in.
An agent that runs on a cloud host or a hosted browser leaves the same fingerprint every time: a datacenter egress IP that anti-bot systems already score as automation, a single address shared by every task the agent runs in parallel, and a location that matches the hosting region rather than the user it is working for. Each of those signals is enough on its own to trigger a challenge page; together they turn a research task into a stream of CAPTCHAs, empty shells and 403s.
The model does not see any of this. It receives a blocked page, tries to reason about it, and burns tokens on retries. Putting the agent's HTTP traffic behind a residential proxy replaces the datacenter fingerprint with an ordinary household connection, spreads concurrent tasks across many addresses and lets you choose the country the page should be served for.
There is no single best proxy for AI agents; it depends on what the agent does. Fetch-heavy agents that read many pages once, such as research or price-comparison agents, want rotating Residential Basic: every request can come from a different IP, so no single address accumulates a suspicious request count. Agents that log in, fill a cart or step through a multi-page form need a sticky residential session, so the site sees one visitor for the whole flow.
Two special cases: agents that drive consumer apps or social platforms usually fare better on mobile 4G/5G IPs with carrier targeting, and agents that must present the same identity every day, for example a monitoring agent for a single account, fit an ISP proxy, a dedicated static residential IP with unmetered bandwidth for $3.80 per month.
Every Quantum Proxies product is a standard HTTP/HTTPS or SOCKS5 proxy with user:pass authentication or IP whitelisting, so it plugs into whatever your agent already uses for browsing. In Playwright and Puppeteer you pass the proxy server and credentials when launching the browser; in Python the same endpoint goes into the proxies argument of requests or httpx; in Browser Use, Operator-style agents and other browser automation frameworks it is the same launch option under a different name. No SDK of ours is required.
Country, city, session type and session duration are encoded in the proxy username, so an agent can request a US sticky session for a checkout and a rotating German session for a search without touching its code. Generate credentials once in the dashboard, keep them in your agent's environment, and the framework does the rest.
If you build with Claude, Cursor or another MCP-capable client, you can skip proxy configuration altogether. The Quantum Proxies MCP server at /mcp-server exposes search, scrape, crawl and map tools to the model, and every call already routes through the residential network; the agent asks for a page and gets it back, geo-targeted, without handling IPs.
For pipelines that feed pages into a model, the Extract API at /extract-api fetches a URL through the proxy layer and returns clean Markdown, which costs far fewer tokens than raw HTML and drops navigation, scripts and boilerplate. The SERP API at /serp-api returns structured search results for a query and location, so a research agent can go from question to sources in one call. All three bill from the same wallet as the raw proxies.
Agents are unpredictable consumers: one task fetches three pages, the next fetches three thousand. Per-GB pricing fits that pattern better than a monthly seat. Residential Basic costs $1.00 per GB on the 25 GB plan and $0.80 per GB on the 1,000 GB plan, with 90–360 days of validity, and there is no subscription: unused traffic simply waits for the next job.
The arithmetic is worth doing once. A typical HTML page is roughly 60 KB without images, so 1 GB is about 1,000,000 KB ÷ 60 ≈ 16,000 pages, call it roughly 15,000 to leave room for heavier pages. At $0.80–$1.00 per GB, 1,000 pages cost roughly $0.05–$0.07. Requesting HTML only, or using the Extract API to return Markdown, keeps the per-page figure at that end of the range.
An agent running unattended needs a budget it cannot exceed. The wallet gives you one: top up any amount from $5, the balance never expires, and when it is gone the proxy stops serving requests rather than running up a bill. That is a hard ceiling on what a runaway loop can spend. For agents that must not stall, enable auto-recharge with a threshold and a top-up amount of your choosing, and switch it off again when the job ends.
Usage is visible per credential in the dashboard, so you can give each agent its own proxy user and see exactly which one consumed the traffic. Payment is by card, PayPal or 300+ cryptocurrencies with no KYC, so a side project can fund its agent without a company card on file.
Much of what an agent is asked to do depends on where the request comes from: prices shown in the local currency, search results for a city, availability in a region, content that only serves a given country. A residential proxy with country and city targeting makes the agent appear to be there, so the page it reads is the page a local user would see. Residential Basic covers 200+ countries with city targeting; mobile adds region and carrier selection across 194 countries; ISP proxies offer static IPs in 25 countries.
Combined with the SERP API's location parameter, an agent can compare the same query from several markets in one run, which is the kind of task that is impossible from a single datacenter IP.
| Task | Proxy type | Session | Why |
|---|---|---|---|
| Research agent reading hundreds of pages | Residential Basic | Rotating | Each request from a different household IP; no single address builds up a suspicious request count |
| Login, cart or multi-step form | Residential Basic or Premium | Sticky | The site sees one consistent visitor across the whole flow |
| Search results by city or country | Residential Basic or SERP API | Rotating, geo-targeted | Pages and rankings match what a local user would see |
| Consumer app or social platform automation | Mobile 4G/5G | Sticky, up to 24 h | Real carrier IPs with carrier and region targeting |
| Daily monitoring of one account | ISP / static residential | Fixed IP | Same identity every day, unmetered bandwidth, $3.80 per IP per month |
| Feeding pages to an LLM | Extract API | Handled for you | Returns Markdown through the proxy layer; fewer tokens than raw HTML |
| Claude or Cursor needing live web access | MCP server | Handled for you | Search, scrape, crawl and map tools with proxies built in |
Yes. Quantum Proxies are standard HTTP/HTTPS and SOCKS5 proxies, so they work with any framework whose tools make web requests: pass the proxy endpoint and credentials to the HTTP client, browser launcher or fetch tool the framework uses. Nothing is specific to one agent library, and no proprietary SDK is needed.
The MCP server at /mcp-server gives an MCP-capable client such as Claude or Cursor ready-made tools for search, scrape, crawl and map, each already routed through the residential network. The model calls a tool and receives the page or results; you never configure IPs, sessions or geo targeting in the agent itself. It bills from the same wallet.
Roughly $0.05–$0.07 on Residential Basic. The arithmetic: a typical HTML page is about 60 KB, so 1 GB ≈ 1,000,000 KB ÷ 60 ≈ 16,000 pages, call it roughly 15,000. At $0.80–$1.00 per GB, 1,000 pages come to a few cents. Heavier pages or media raise the figure; HTML-only requests or Markdown from the Extract API lower it.
Use rotating sessions when the agent reads many independent pages, so each request comes from a different IP and no address accumulates a suspicious pattern. Use sticky sessions when the agent must look like one visitor across several steps, for example a login followed by a dashboard or a checkout. Both are selected per request through the proxy username.
For public pages that do not fight automation, datacenter traffic from $0.50 per GB is the cheaper choice. Most sites an agent is actually sent to, from retailers to search engines to social platforms, score datacenter ranges as automation, so residential IPs are the practical default. Start with residential, and move bulk, low-friction fetching to datacenter to save money.
Yes. Alongside card and PayPal, the wallet accepts 300+ cryptocurrencies including USDT, with no KYC. Top up any amount from $5; the balance never expires and funds raw proxies, the MCP server, the Extract API and the SERP API alike. Every purchase is one-off, with no subscription or recurring billing agreement.
Yes. New accounts get 100 MB of Residential Basic traffic free for 5 days, one per person, unlocked by a one-time SMS verification in Settings → Free Trial, no card required. At roughly 60 KB per page that is enough for a few hundred to a couple of thousand agent fetches, plenty to confirm the target site and session type before buying.
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.
