The platform is based on two independent pools. The first one is a premium private modem pool: physical 4G/5G devices with real SIM cards from mobile operators. This pool is best suited for sensitive tasks where stability, trust, and long session quality matter most. The second one is an SDK-based network of real mobile and residential devices connected directly to Proxies.sx infrastructure. This network gives broader GEO coverage, helps reach rare regions, and makes the IP pool more diverse and scalable.

Proxies.sx can be used for automation, account management, data collection, web scraping, affiliate marketing, SEO monitoring, ad verification, marketplace analysis, e-commerce checks, AI systems, and reseller projects. The service supports both precise controlled setups and large-scale automated workflows. Users can create dedicated proxy ports through the dashboard or API, configure IP rotation, use sticky sessions, and manage traffic rules depending on their task.

The service supports Shared and Private proxies. Shared proxies are suitable for scalable and cost-efficient tasks, while Private proxies provide more isolation and control for sensitive accounts, commercial workflows, and long-term sessions. Proxies.sx also provides a unified Pool Gateway, where the system automatically selects a suitable IP for each request. Dedicated ports and the Pool Gateway can be used together, depending on the workflow.

The platform supports HTTP and SOCKS5 protocols, REST API, webhooks, SDK-based integrations, and MCP for AI systems and automated tools. This makes Proxies.sx useful not only as a proxy provider, but also as infrastructure for developers, automation teams, data teams, and resellers who want to build their own proxy-related products.

One of the main advantages of Proxies.sx is its billing model. There is no mandatory slot rental, no time-based proxy rental, and no hidden subscription logic. Users pay only for the traffic they actually consume. This makes the service especially convenient for teams with uneven workloads, testing scenarios, scraping pipelines, automation tasks, and AI systems where traffic usage can vary.

Proxies.sx supports more than 70 countries. The premium modem pool covers many popular GEOs such as the United States, the United Kingdom, Germany, France, Poland, Spain, Italy, the Netherlands, Japan, Singapore, and others. The SDK-based network expands coverage further, including less common regions across Latin America, Africa, and Asia. New IPs and new locations are added regularly.

All devices inside the network are continuously monitored. If an IP becomes unstable, low-quality, or unsuitable for production use, it is removed from rotation. The service also supports automatic replacement of problematic ports, helping users maintain stable operations without unnecessary manual work.

Payment options include bank cards, USDT, CoinGate, and more than 200 cryptocurrencies. The platform also supports direct crypto transfers and x402 payments for AI systems. A single internal balance can be used for different proxy types without unnecessary restrictions.

Proxies.sx is also suitable for resellers and partners. The platform provides API access, webhook integrations, SDK tools, and ready infrastructure that can be used to build custom proxy services under another brand.
