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.

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.

MethodHowCooldown
ManualCall the rotation URL from your proxy credentials5 minutes
AutomaticConfigure interval (5-1440 minutes)Per interval
Public URLRotation token URL — no auth needed5 minutes
# 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:

EndpointDescription
GET /v1/x402/manage/sessionSession details (traffic used, time remaining)
GET /v1/x402/manage/session/creditCheck remaining credit
GET /v1/x402/manage/portsList ports in session
POST /v1/x402/manage/ports/recreateRecreate expired port (if credit remains)
POST /v1/x402/manage/ports/replaceReplace offline port (free, max 3)
POST /v1/x402/manage/session/topupAdd more traffic (pay additional USDC)
# 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.

Proxy TypeBlock RateTrust LevelCostUse Case
DatacenterHigh (~80%)Low$0.50/GBBasic requests only
ResidentialMedium (~30%)Medium$2-5/GBGeneral scraping
Mobile 4G/5GVery Low (~5%)High$4-8/GBEverything — highest success rate

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.

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 55 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.
