Smartproxy + CaptchaAI: Residential Proxy Setup for CAPTCHA Solving

Smartproxy provides 55M+ residential IPs with a simple rotating gateway. Combined with CaptchaAI for CAPTCHA solving, you get a reliable pipeline for accessing CAPTCHA-protected sites through clean residential IPs.

Smartproxy Proxy Types

Python Setup

Basic Requests

import requests
import time

SMARTPROXY_USER = "spuser"
SMARTPROXY_PASS = "sppassword"
SMARTPROXY_HOST = "gate.smartproxy.com"
SMARTPROXY_PORT = 10001

CAPTCHAAI_KEY = "YOUR_API_KEY"
CAPTCHAAI_URL = "https://ocr.captchaai.com"

proxies = {
    "http": f"http://{SMARTPROXY_USER}:{SMARTPROXY_PASS}@{SMARTPROXY_HOST}:{SMARTPROXY_PORT}",
    "https": f"http://{SMARTPROXY_USER}:{SMARTPROXY_PASS}@{SMARTPROXY_HOST}:{SMARTPROXY_PORT}",
}


def fetch_page(url):
    return requests.get(url, proxies=proxies, timeout=30)


def solve_captcha(site_url, sitekey, captcha_type="recaptcha_v2"):
    submit_data = {
        "key": CAPTCHAAI_KEY,
        "pageurl": site_url,
        "json": 1,
    }

    if captcha_type == "turnstile":
        submit_data["method"] = "turnstile"
        submit_data["sitekey"] = sitekey
    else:
        submit_data["method"] = "userrecaptcha"
        submit_data["googlekey"] = sitekey

    resp = requests.post(f"{CAPTCHAAI_URL}/in.php", data=submit_data)
    data = resp.json()
    if data["status"] != 1:
        raise Exception(f"Submit failed: {data['request']}")

    task_id = data["request"]

    for _ in range(60):
        time.sleep(5)
        resp = requests.get(f"{CAPTCHAAI_URL}/res.php", params={
            "key": CAPTCHAAI_KEY,
            "action": "get",
            "id": task_id,
            "json": 1,
        })
        data = resp.json()
        if data["request"] == "CAPCHA_NOT_READY":
            continue
        if data["status"] == 1:
            return data["request"]
        raise Exception(f"Solve: {data['request']}")

    raise TimeoutError("Timeout")

Sticky Sessions

import random
import string


def get_sticky_proxy(session_duration_minutes=10):
    """Create a sticky session proxy (same IP for duration)."""
    session_id = "".join(random.choices(string.ascii_lowercase + string.digits, k=8))

    proxy_url = (
        f"http://{SMARTPROXY_USER}"
        f"-session-{session_id}"
        f"-sessionduration-{session_duration_minutes}"
        f":{SMARTPROXY_PASS}@{SMARTPROXY_HOST}:{SMARTPROXY_PORT}"
    )

    return {"http": proxy_url, "https": proxy_url}


# Use same IP for entire CAPTCHA workflow
sticky = get_sticky_proxy(session_duration_minutes=10)

# Page load
resp = requests.get("https://target.com/form", proxies=sticky)

# Solve CAPTCHA
token = solve_captcha("https://target.com/form", "SITEKEY_HERE")

# Submit with same IP
resp = requests.post(
    "https://target.com/submit",
    data={"g-recaptcha-response": token},
    proxies=sticky,
)

Country Targeting

# Smartproxy country targeting via username
def get_country_proxy(country_code):
    proxy_url = (
        f"http://{SMARTPROXY_USER}"
        f"-country-{country_code}"
        f":{SMARTPROXY_PASS}@{SMARTPROXY_HOST}:{SMARTPROXY_PORT}"
    )
    return {"http": proxy_url, "https": proxy_url}

# US proxy
us_proxy = get_country_proxy("us")

# UK proxy
uk_proxy = get_country_proxy("gb")

# Germany proxy
de_proxy = get_country_proxy("de")

Selenium Integration

from selenium import webdriver
from selenium.webdriver.common.by import By


def create_smartproxy_driver(country=None, sticky_session=None):
    proxy_user = SMARTPROXY_USER
    if country:
        proxy_user += f"-country-{country}"
    if sticky_session:
        proxy_user += f"-session-{sticky_session}"

    proxy_url = f"{proxy_user}:{SMARTPROXY_PASS}@{SMARTPROXY_HOST}:{SMARTPROXY_PORT}"

    options = webdriver.ChromeOptions()
    options.add_argument(f"--proxy-server=http://{SMARTPROXY_HOST}:{SMARTPROXY_PORT}")
    options.add_argument("--disable-blink-features=AutomationControlled")
    options.add_argument("--window-size=1920,1080")

    # For authenticated proxies, use seleniumwire or extension
    return webdriver.Chrome(options=options)


def scrape_with_captcha(url, country="us"):
    session_id = "".join(random.choices(string.ascii_lowercase, k=8))
    driver = create_smartproxy_driver(country=country, sticky_session=session_id)

    try:
        driver.get(url)
        time.sleep(3)

        sitekey = driver.execute_script(
            "return document.querySelector('[data-sitekey]')?.getAttribute('data-sitekey')"
        )

        if sitekey:
            token = solve_captcha(url, sitekey)
            driver.execute_script(f"""
                document.querySelector('#g-recaptcha-response').value = '{token}';
            """)
            driver.find_element(By.CSS_SELECTOR, "form").submit()
            time.sleep(3)

        return driver.page_source

    finally:
        driver.quit()

Node.js Integration

const axios = require("axios");
const HttpsProxyAgent = require("https-proxy-agent");

const CAPTCHAAI_KEY = "YOUR_API_KEY";

function getSmartproxyAgent(options = {}) {
  let user = "spuser";
  if (options.country) user += `-country-${options.country}`;
  if (options.session) user += `-session-${options.session}`;

  return new HttpsProxyAgent(
    `http://${user}:sppassword@gate.smartproxy.com:10001`
  );
}

async function scrapeWithCaptcha(url, sitekey) {
  const agent = getSmartproxyAgent({
    country: "us",
    session: `sess-${Date.now()}`,
  });

  // Fetch page through proxy
  const pageResp = await axios.get(url, { httpsAgent: agent });

  // Solve CAPTCHA via CaptchaAI (no proxy needed)
  const submitResp = await axios.post(
    "https://ocr.captchaai.com/in.php",
    null,
    {
      params: {
        key: CAPTCHAAI_KEY,
        method: "userrecaptcha",
        googlekey: sitekey,
        pageurl: url,
        json: 1,
      },
    }
  );

  const taskId = submitResp.data.request;

  // Poll for result
  for (let i = 0; i < 60; i++) {
    await new Promise((r) => setTimeout(r, 5000));

    const result = await axios.get("https://ocr.captchaai.com/res.php", {
      params: {
        key: CAPTCHAAI_KEY,
        action: "get",
        id: taskId,
        json: 1,
      },
    });

    if (result.data.request === "CAPCHA_NOT_READY") continue;
    if (result.data.status === 1) return result.data.request;
  }

  throw new Error("Timeout");
}

Concurrent Scraping Pipeline

from concurrent.futures import ThreadPoolExecutor, as_completed


def process_url(url):
    session_id = "".join(random.choices(string.ascii_lowercase, k=8))
    proxy = get_sticky_proxy(10)

    try:
        resp = requests.get(url, proxies=proxy, timeout=30)

        # Check if CAPTCHA is present (simplified detection)
        if "data-sitekey" in resp.text:
            import re
            match = re.search(r'data-sitekey="([^"]+)"', resp.text)
            if match:
                sitekey = match.group(1)
                token = solve_captcha(url, sitekey)
                return {"url": url, "status": "solved", "token": token[:30]}

        return {"url": url, "status": "no_captcha"}

    except Exception as e:
        return {"url": url, "status": "error", "error": str(e)}


urls = [
    "https://site1.com/page",
    "https://site2.com/page",
    "https://site3.com/page",
]

with ThreadPoolExecutor(max_workers=5) as executor:
    futures = {executor.submit(process_url, u): u for u in urls}

    for future in as_completed(futures):
        result = future.result()
        print(f"[{result['status']}] {result['url']}")

Troubleshooting

FAQ

Can I pass Smartproxy IPs to CaptchaAI?

Yes. CaptchaAI accepts a proxy parameter in the submit request. This makes CaptchaAI solve from the same IP as your browser.

Which Smartproxy plan works best for CAPTCHA workflows?

The residential plan with sticky sessions. Pay-as-you-go is cost-effective for moderate volumes. Enterprise plans offer guaranteed bandwidth.

How long should sticky sessions be?

10 minutes covers most CAPTCHA workflows (page load → solve → submit). Extend to 30 minutes for multi-step forms.
