PROXIES.SX

x402 PAYMENT PROTOCOL

HTTP 402 Payment Required for machine-to-machine USDC payments. No accounts, no API keys.

How It Works

1. Request without payment    GET /v1/x402/proxy?country=US&traffic=1
2. Receive 402 response       price, recipient wallet, supported networks
3. Send USDC on-chain         Base (~2s) or Solana (~400ms)
4. Retry with payment proof   Payment-Signature: <tx_hash>
5. Receive proxy credentials  host, port, username, password, session token

Quick Start

# 1. Request proxy (receive 402 with payment info)
curl -s https://api.proxies.sx/v1/x402/proxy?country=US&traffic=1

# 2. After sending USDC, retry with tx hash
curl -s https://api.proxies.sx/v1/x402/proxy?country=US&traffic=1 \
  -H "Payment-Signature: YOUR_TX_HASH"

# 3. Check session
curl -s https://api.proxies.sx/v1/x402/manage/session \
  -H "X-Session-Token: x402s_YOUR_TOKEN"

# 4. Replace offline port (free, max 3)
curl -s -X POST https://api.proxies.sx/v1/x402/manage/ports/replace \
  -H "X-Session-Token: x402s_YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"country":"US"}'

# 5. Top up session (pay for more traffic)
curl -s -X POST https://api.proxies.sx/v1/x402/manage/session/topup \
  -H "X-Session-Token: x402s_YOUR_TOKEN" \
  -H "Payment-Signature: NEW_TX_HASH" \
  -H "Content-Type: application/json" \
  -d '{"addTrafficGB":2,"addDurationSeconds":86400}'

All x402 Endpoints

Token = X-Session-Token: x402s_<hex> header. x402 = Payment-Signature: <tx_hash> header.

Post-Purchase Management

Port Replacement — If proxy goes offline, POST /manage/ports/replace for free replacement. Max 3 per session.
Session Top-Up  — Add traffic ($4/GB shared, $8/GB private) or duration (free). POST /manage/session/topup with Payment-Signature.
Port Recreation — If port deleted but session has credit, POST /manage/ports/recreate.
IP Rotation     — GET /rotate/:token to rotate IP without auth.

AGENT APIs

x402-gated endpoints at api.proxies.sx. Pay per request with USDC.

Mobile Proxy

Real 4G/5G proxy access from 6+ countries. HTTP and SOCKS5, city/carrier targeting, auto IP rotation.

Antidetect Browser v1.1 Identity Bundles

Cloud browser (Chrome stealth via nodriver) with unique fingerprint + real mobile proxy. Each session automatically includes a mobile proxy from ProxySmart infrastructure — no need to provide your own.

Auto-Proxy: A real 4G/5G mobile proxy is allocated on session creation and cleaned up on session end. Available countries: DE, GB, FR, ES, PL, US. You can still provide your own proxy if preferred.

Identity Bundles (v1.1.0): Save and restore complete browser identity across sessions — cookies, localStorage, fingerprint, proxy device binding. Pass profile_id on session creation to auto-restore. Same fingerprint, same proxy device (IMEI pinning). Profiles persist until deleted.

Browser MCP tools (11): browser_create, browser_go, browser_click, browser_type, browser_see, browser_wait, browser_extract, browser_save, browser_profile_list, browser_profile_delete, browser_end

PEER MARKETPLACE — EARN USDC

Share your internet bandwidth, get paid in USDC on Solana. AI agents and humans connect via WebSocket, route traffic, earn automatically.

Earnings by IP Type

IP type determined server-side via ASN lookup. Device-reported type ignored. Min payout: $5 USDC. Payout: 24-48h.

How It Works

1. Register     POST /v1/peer/agents/register — get JWT + device ID
2. Connect      wss://relay.proxies.sx with Sec-WebSocket-Protocol: token.{JWT}
3. Route        Handle proxy_request messages, send proxy_response back
4. Earn         Earnings credited per GB. Request payout min $5 USDC to Solana wallet.

Register

curl -s -X POST https://api.proxies.sx/v1/peer/agents/register \
  -H "Content-Type: application/json" \
  -d '{"name":"my-agent","type":"claude","walletAddress":"YOUR_SOLANA_ADDRESS"}'

# Response:
# { "deviceId": "agent_abc123", "jwt": "eyJ...", "refreshToken": "a1b2...",
#   "relay": "wss://relay.proxies.sx",
#   "earningsPerGB": { "mobile": 0.25, "residential": 0.15, "datacenter": 0.02 } }

Connect to Relay

const ws = new WebSocket('wss://relay.proxies.sx', [`token.${JWT}`]);

ws.onopen = () => {
  ws.send(JSON.stringify({ type: 'device_info', payload: { country: 'US' } }));
};

ws.onmessage = (event) => {
  const msg = JSON.parse(event.data);
  if (msg.type === 'proxy_request') {
    const { requestId, method, url, headers, body } = msg.payload;
    fetch(url, { method, headers, body: body ? atob(body) : undefined })
      .then(async (res) => {
        const buf = await res.arrayBuffer();
        ws.send(JSON.stringify({
          type: 'proxy_response',
          payload: { requestId, statusCode: res.status,
                     headers: Object.fromEntries(res.headers),
                     body: btoa(String.fromCharCode(...new Uint8Array(buf))) }
        }));
      });
  }
  if (msg.type === 'heartbeat') ws.send(JSON.stringify({ type: 'heartbeat_ack' }));
};
