The mobile proxy API you can paste into anything

curl

export PROXY_URL="http://USERNAME-mbl-us-rot-sticky:[email protected]:7000"

curl -x "$PROXY_URL" https://api.ipify.org?format=json

Python

import os, requests

proxy = os.environ["PROXY_URL"]

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

Node.js

import { HttpsProxyAgent } from 'https-proxy-agent';

const agent = new HttpsProxyAgent(process.env.PROXY_URL);

const res = await fetch('https://api.ipify.org?format=json', { agent });
console.log(await res.json());

Playwright

import { chromium } from 'playwright';

const url = new URL(process.env.PROXY_URL);

const browser = await chromium.launch({
  proxy: {
    server: `http://${url.host}`,
    username: decodeURIComponent(url.username),
    password: decodeURIComponent(url.password),
  },
});

Nothing for the model to hallucinate

Coding assistants already know how to set a proxy in requests, axios, httpx, Playwright and Puppeteer — it is in every framework's documentation and has been for a decade. Ask for "route this through my proxy" and you get working code on the first try, because there is no ProxyMobile-specific SDK surface for the model to guess at.

One environment variable is the whole integration

Drop PROXY_URL into your .env and pass it wherever your HTTP client takes a proxy. That is the entire change. Nothing in your request-building, retry or parsing logic has to know a proxy exists, so you can add or remove it from a working project without touching the parts you had trouble getting right.

Change country or rotation without changing code

The username carries the routing: swap -us- for -de- to move country, or -rot-sticky for -rot-auto10 to rotate every ten minutes. In a vibe-coded project this matters — you can tune behaviour from a config value or an env var instead of asking a model to refactor a working file.

It fails in ways you can read

Because it is an ordinary proxy, a bad key is a 407 and a blocked target is whatever that site returns. You debug with the tools and error messages you already understand rather than decoding a vendor-specific error envelope.

Ad verification

Check that a campaign renders the way it should for a real subscriber on a real carrier, in the country you bought the placement in. Mobile IPs matter here because ad servers treat datacentre traffic differently — often serving a different creative, or nothing at all.

Price and marketplace monitoring

Track competitor pricing, stock and shipping estimates across regions. Retail sites localise heavily and rate-limit aggressively, so a rotating mobile pool gets you consistent reads where a fixed IP gets stale prices or a block page.

SERP and rank tracking

Search results differ by country, carrier and device class. Querying through mobile IPs in the market you care about gives you the ranking a real user in that market sees, rather than a datacentre approximation of it.

AI agents and browser automation

Agents that browse — research crawlers, shopping bots, QA runners — hit bot walls fast from a cloud IP, because the whole datacentre range is known. Pointing the agent's browser at a mobile proxy is a one-line change in Playwright or Puppeteer and removes an entire class of failure.

Web scraping and data collection

Long crawls survive better on carrier IPs that rotate on a schedule you control. Set auto10, run the job, and pay for the gigabytes you moved rather than a per-request markup.

QA and geo-testing

Test the localised build of your own app or checkout flow — currency, language, tax, shipping rules, geo-gated content — from inside the market instead of guessing what a user there would see.

Market and review research

Aggregate listings, reviews and availability across regions for research, without your own office IP shaping the results you get back.
