Drop into your code

Same username string works in every language and every proxy-aware library. Copy whichever fits your stack.

Python · requests

python
import requests

PROXY = "http://psx_YOUR_ID-mbl-us:YOUR_PROXY_PASSWORD@gw.proxies.sx:7000"
proxies = {"http": PROXY, "https": PROXY}

r = requests.get("https://api.ipify.org?format=json", proxies=proxies, timeout=30)
print(r.json())

Node.js · Playwright

javascript
// Playwright with proxy
import { chromium } from 'playwright';

const browser = await chromium.launch({
  proxy: {
    server: 'http://gw.proxies.sx:7000',
    username: 'psx_YOUR_ID-mbl-us',
    password: 'YOUR_PROXY_PASSWORD',
  },
});

Multi-account loop · sticky session per account

python
# 100 separate accounts, each on its own consistent IP
import requests, secrets

for account_id in range(100):
    sid = f"acct{account_id:03d}_{secrets.token_hex(4)}"
    proxy = f"http://psx_YOUR_ID-mbl-us-sid-{sid}:YOUR_PROXY_PASSWORD@gw.proxies.sx:7000"
    proxies = {"http": proxy, "https": proxy}
    # ... use proxies for this account's session ...

Token reference

The full vocabulary. Mix and match — order matters only for required tokens (account, pool, country). Optional tokens come after, in any order.

FAQ

Where do I get my account ID and password?
Sign in to client.proxies.sx and copy the psx_ account ID + proxy password from your dashboard. Both are needed to authenticate.
What's the difference between Random and Sticky session?
Random gets a new endpoint per connection (best for stateless scraping). Sticky pins all connections sharing the same sid to the same modem (best for multi-step browsing or one-IP-per-account).
Why are sticky session IDs validated?
Common values like "test", "demo", "user", "admin", and sequential numbers are rejected so two customers don't accidentally collide on the same session. Pick something random per account.
Can I combine carrier + city + sticky + rotation?
Yes. The tokens compose freely. Example: psx_X-mbl-us-city-newyork-carrier-tmobile-sid-job42-rot-sticky = a NYC T-Mobile IP that stays the same for the duration of the session.
What if my chosen city or carrier has no online modems?
The gateway falls back according to your failover policy. Default is samecountry. Set strict if you want a 502 error instead of a fallback.
Does this work with Playwright / Puppeteer / Selenium?
Yes — they all accept standard HTTP/SOCKS5 proxy auth. Pass the username + password as proxy credentials and you're done.
How fast does it switch when I change the username?
Instant. There's no provisioning lag — the gateway parses your username on every connection and routes accordingly. You can change country/carrier/rotation per request if you want.

Generate a string above, paste it into curl, see a real mobile IP.

The Pool Gateway routes through real T-Mobile, Vodafone, EE, Orange, and Telefónica modems. Pay only for the GB you actually use.
