Sc Vpn

SC-VPN Gateway

Internal VPN service for the Starchild platform. Provides exit nodes in 18 fixed countries — accessible only from within the Starchild internal network. No credentials or setup needed.

⚠️ When to Use

SC-VPN is a last resort, not a default. Most agent HTTP traffic already goes through sc-proxy (the platform's transparent billing proxy for paid APIs). Setting a global VPN proxy will break sc-proxy routing.

Use SC-VPN only when:

• A specific request is geo-blocked or returns a region error
• You need to appear from a specific country for a particular API call
• A target website/API refuses connections from the default exit

Always use per-request proxy (pass proxies= to requests.get() or -x to curl). Never set global `HTTP_PROXY` / `HTTPS_PROXY` environment variables

Available Countries

Only these 18 countries. Requests for other regions are rejected (502). The specific server per country is auto-selected daily based on latency.

Quick Start

curl (per-request proxy)

# Route ONE request through Japan
curl -x "http://jp:x@sc-vpn.internal:8080" https://ifconfig.me

# Route ONE request through Brazil
curl -x "http://br:x@sc-vpn.internal:8080" https://example.com/api

Python requests (per-request proxy)

import requests

def vpn_proxy(region: str) -> dict:
    """Return proxy dict for a given region code."""
    return {
        "https": f"http://{region}:x@sc-vpn.internal:8080",
        "http":  f"http://{region}:x@sc-vpn.internal:8080",
    }

# Only the geo-blocked request goes through VPN
resp = requests.get("https://geo-restricted-api.example.com", proxies=vpn_proxy("jp"))

# All other requests go through normal sc-proxy routing (no proxies= arg)
resp2 = requests.get("https://api.coingecko.com/...")

❌ Do NOT do this

# WRONG — may influence other requests
export HTTP_PROXY="http://jp:x@sc-vpn.internal:8080"
export HTTPS_PROXY="http://jp:x@sc-vpn.internal:8080"

Region Selection

The username in the proxy URL selects the exit country:

REST API

Base URL: http://sc-vpn.internal:8081

Rate Limits

Clients identified by source IP. No API keys needed — internal network only.

Verify It Works

# Your real exit IP
curl https://ifconfig.me

# VPN exit IP (should be different, from Japan)
curl -x "http://jp:x@sc-vpn.internal:8080" https://ifconfig.me
