MOBILE PROXY API

WHAT IT IS

A mobile proxy API that gives you real 4G/5G IP addresses from physical phone and modem devices. Every request routes through a real carrier network - AT&T, T-Mobile, Vodafone, Orange, Deutsche Telekom - making your traffic indistinguishable from a real mobile user.

Pay with USDC on Base or Solana via the x402 protocol. No account registration. No API key. No subscription. Just send a request, pay on-chain, and get proxy credentials.

PRICING

Duration is free. You only pay for traffic.

Cost Per Request (Typical)

At $4/GB, a typical text scraping operation costs less than $0.001 per request.

HOW TO USE

Step 1: Request a Proxy

curl "https://api.proxies.sx/v1/x402/proxy?country=US&traffic=0.1"

Returns HTTP 402 with payment instructions:

{
  "status": 402,
  "message": "Payment required",
  "price": "400000",
  "currency": "USDC",
  "networks": [
    {
      "network": "base",
      "chainId": "eip155:8453",
      "recipient": "0xF8cD900794245fc36CBE65be9afc23CDF5103042",
      "asset": "USDC",
      "assetAddress": "0x833589fcd6edb6e08f4c7c32d4f71b54bda02913"
    },
    {
      "network": "solana",
      "chainId": "solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp",
      "recipient": "6eUdVwsPArTxwVqEARYGCh4S2qwW2zCs7jSEDRpxydnv",
      "asset": "USDC",
      "assetAddress": "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"
    }
  ]
}

Step 2: Pay USDC On-Chain

Send $0.40 USDC to the recipient wallet on Base (~2s) or Solana (~400ms).

Step 3: Retry with Payment

curl "https://api.proxies.sx/v1/x402/proxy?country=US&traffic=0.1" \
  -H "Payment-Signature: 0xyour_transaction_hash"

Returns proxy credentials:

{
  "host": "proxy.proxies.sx",
  "httpPort": 10234,
  "socksPort": 10235,
  "username": "psx_abc123",
  "password": "r4nd0mP4ss",
  "country": "US",
  "expiresAt": "2026-02-09T05:00:00Z",
  "trafficLimitGB": 0.1,
  "sessionToken": "x402s_abc123def456...",
  "rotationUrl": "https://api.proxies.sx/rotate/tok_xyz789"
}

Step 4: Use the Proxy

# With curl
curl -x http://psx_abc123:r4nd0mP4ss@proxy.proxies.sx:10234 https://httpbin.org/ip

# With Python requests
import requests
proxies = {"http": "http://psx_abc123:r4nd0mP4ss@proxy.proxies.sx:10234",
           "https": "http://psx_abc123:r4nd0mP4ss@proxy.proxies.sx:10234"}
r = requests.get("https://httpbin.org/ip", proxies=proxies)

# With Node.js
const response = await fetch("https://httpbin.org/ip", {
  agent: new HttpsProxyAgent("http://psx_abc123:r4nd0mP4ss@proxy.proxies.sx:10234")
});

IP ROTATION

Rotate your proxy to a new mobile IP on demand - no extra cost.

# Rotate IP via public URL (from proxy credentials)
curl "https://api.proxies.sx/rotate/tok_xyz789"
# -> { "success": true, "newIp": "185.32.xxx.xxx" }

SESSION MANAGEMENT

After purchase, manage your proxy session using the session token:

# Check session status
curl "https://api.proxies.sx/v1/x402/manage/session" \
  -H "X-Session-Token: x402s_abc123def456"

WHY MOBILE PROXIES

Mobile IPs are assigned by carriers (AT&T, T-Mobile, Vodafone) to millions of real users. Websites cannot block mobile IP ranges without blocking their own customers.

Mobile proxies are the most trusted IP type on the internet. Google, Instagram, Amazon, LinkedIn - they all treat mobile IPs as legitimate users because they are legitimate IPs from real carrier networks.

AVAILABLE COUNTRIES

Country availability is live - the mobile fleet rotates as carrier supply changes, so the exact set online varies day to day. Always check the live stock endpoint for what is online right now before you buy:

curl https://api.proxies.sx/v1/gateway/pool/stock
# { "pools": { "mbl": { "us": 24, "gb": 13, "pl": 25, "nl": 26, "ge": 3 } } }

These are the countries we serve when carrier supply is up. Some (ES, DE, FR, GE) rotate in and out - if a country reads 0 in the stock endpoint it is temporarily unavailable, not gone. For EU work, FR / NL / DE mobile behave nearly identically for most use cases.

FOR AI AGENTS

AI coding agents (Claude Code, OpenAI Codex, Opencode) can purchase proxies autonomously using x402. The flow is automatic:

1. Agent calls endpoint -> gets 402 response
2. Agent signs USDC transaction using wallet private key
3. Agent retries with Payment-Signature header
4. Agent receives proxy credentials and starts using them

MCP Server

For AI agents using MCP (Model Context Protocol):

npx @proxies-sx/mcp-server

Provides 73 tools for proxy management. npm package

x402 SDK

npm install @proxies-sx/x402-core @proxies-sx/x402-hono @proxies-sx/x402-solana

Build your own services on top of mobile proxies with payment gating.
