Proxies.sx is an AI-native mobile and residential proxy service with real 4G/5G carrier IP addresses and proprietary infrastructure. Unlike many services on the market, the platform does not resell third-party proxies — the entire network is owned and managed by the Proxies.sx team and continuously updated with new IP addresses.

The service draws on two proprietary sources. The first is a premium pool of 500+ physical 4G/5G modems with real carrier SIM cards, used for stable sessions and important, commercial-grade tasks. The second is an SDK-based network of partner devices spanning 100+ countries, covering both mobile and residential connections — this includes plain residential internet (regular home or office connections), not only SIM-based mobile traffic. This second pool is what powers large-scale scraping, rare geographies, and broad country coverage.

Proxies.sx allows users to create separate proxy ports through a dashboard or API, configure IP rotation flexibly, use sticky sessions, and automatically route traffic for specific tasks. The service supports HTTP, SOCKS5, and a full REST API, and is built with AI agents in mind: an MCP server lets tools like Claude, Cursor, and Cline manage proxy infrastructure through natural language, and an x402 payment endpoint lets AI agents pay per request in USDC (Base or Solana) with no registration, no API keys, and settlement in roughly 2 seconds.

How the Infrastructure Works

PoolIncludesUsed For
Premium modem pool500+ proprietary 4G/5G modems with real carrier SIM cardsImportant accounts, stable sessions, commercial tasks
Mobile & residential device networkProprietary SDK network of partner devices — mobile and
residential, including regular user internet connections
Large-scale scraping, rare geographies, broad country coverage

All devices in the network undergo continuous quality monitoring. Problematic IPs are automatically removed from rotation to keep connections stable.

Built for AI Agents

Proxies.sx is built to be used by autonomous AI systems, not just humans:

  • x402 protocol — AI agents pay per request in USDC (Base or Solana), no registration or API keys, settlement in ~2 seconds, minimum purchase $0.375
  • MCP server — 55 tools for controlling proxy infrastructure through natural language in Claude, Cursor, and Cline
  • Peer Network — anyone can run a proxy agent on their own device (phone, VPS, or residential connection) and earn USDC per GB of bandwidth shared, with automatic classification by connection type and payouts to a Solana wallet ($5 minimum)

Data Works — Done-for-You Data

For teams that don't want to run their own scrapers: send Proxies.sx a URL and the fields you need, and the team runs the extraction on its own 4G/5G infrastructure, handling anti-bot systems (DataDome, Cloudflare, PerimeterX-class defenses) on their side. Delivery is QA-checked CSV, JSON, or API, on a schedule, billed as a flat monthly retainer.

FAQ — Popular Questions About Proxies.sx

Are these real mobile IPs? 

Yes. Proxies.sx works with genuine 4G/5G carrier IPs rather than datacenter proxies disguised as mobile IPs. The network is based on a proprietary pool of 500+ physical modems with carrier SIM cards, plus a partner device network covering both mobile and residential connections — this makes IPs appear more natural to platforms and increases their trust level.

How many countries are available? 

100+ countries. The premium modem pool covers 30+ popular geo locations including the USA, UK, Germany, France, Poland, Spain, Italy, the Netherlands, Japan, and Singapore. The wider partner device network extends coverage into rarer regions across Latin America, Africa, and Asia. New IPs and countries are added almost daily.

How does pricing work? 

One simple model: pay per GB of real 4G/5G mobile and residential traffic, from $4/GB down to $2.40/GB at volume. Endpoints, unlimited IP rotation, and 24/7 support are all free, and bandwidth never expires.

Does bandwidth expire? 

Never. Buy bandwidth once, use it whenever you like — your GB balance rolls over indefinitely.

How fast can I rotate IPs? 

Instantly and as often as you like — on demand via API, by sticky-session token, or on an automatic interval (5–1440 minutes). Rotations are always free and unlimited.

What is CGNAT and why does it matter? 

Carrier-Grade NAT is how mobile networks share public IPs among many users. Platforms expect to see multiple accounts from a single mobile IP — it's normal mobile behavior, which is why mobile proxies carry more trust than datacenter IPs.

Can I choose my country? 

Yes. Select your country when creating an endpoint, and choose city, mobile carrier, ASN, or ISP as well — useful for tasks that need precise traffic geography. You can also rotate across the full device pool.

How do cryptocurrency payments work? 

Users can top up their balance via CoinGate (50+ cryptocurrencies), direct USDT/TRON transfers, or x402 for AI agents. The balance is shared across the service and can be used for any proxy type.

What is the difference between dedicated ports and Pool Gateway? 

Dedicated ports give more control and suit account management, long sessions, and tasks requiring a specific IP. Pool Gateway automatically selects a suitable IP for each request, which is convenient for mass scraping, automation, and large-scale traffic. Both modes can be used at the same time.

Is the device network reselling third-party proxies? 

No — it's Proxies.sx's own infrastructure. The service uses its own SDK, integrated by partners into their applications, and devices connect directly to Proxies.sx. For users, this means a continuously growing IP pool, fresher addresses with fewer blocks, broad country and carrier coverage, and more natural IP geography.

What happens if an IP stops working? 

The system continuously monitors device and connection quality. Unstable IPs are quickly removed from rotation, and automatic free replacement is available for problematic ports.

Is there an API? 

Yes. The API manages proxies, IP rotation, countries, carriers, balances, and other settings. Proxies.sx also supports MCP for AI agents and automation tools.

Can one IP stay fixed for a long period? 

Yes — sticky sessions let you keep the same IP over extended periods, useful for account management, automation, and services that require stable sessions.

Is support available? 

Yes, 24/7, via ticket system or Telegram: @sxproxies.

Is Proxies.sx suitable for resellers? 

Yes. Proxies.sx can power custom proxy services under your own brand, with API, webhook integrations, SDK, and ready-made infrastructure for partners and resellers.

Can AI agents use Proxies.sx directly? 

Yes. Through the x402 protocol, AI agents can pay for proxy access in USDC (Base or Solana) with no accounts, no KYC, and no API keys — just an HTTP 402 payment that settles in about 2 seconds. Proxies.sx also runs an MCP server with 55 tools for direct control from Claude, Cursor, and Cline.
