Proxies for web scraping

Which proxy type should you use for scraping?Copy Anchor Link

How to avoid blocks when scrapingCopy Anchor Link

1. Rotate IPs. With a residential pool, every request can exit from a different IP.
2. Keep sessions consistent. If a site sets cookies on one page and checks them on the next, send both requests through the same sticky session.
3. Limit concurrency per site. Hundreds of parallel requests to one domain look like an attack, whatever the IP.
4. Send realistic headers. A current browser User-Agent, Accept-Language and normal header order.
5. Retry with backoff. Treat 403, 429 and timeouts as signals to slow down and switch IP.
6. Target the right country. Prices and content often change by region, so pick IPs in the market you are measuring.

import random
import time

import requests

PROXY = "http://USERNAME:PASSWORD@HOST:PORT"  # values from your dashboard
proxies = {"http": PROXY, "https": PROXY}
headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 "
    "(KHTML, like Gecko) Chrome/128.0 Safari/537.36",
    "Accept-Language": "en-US,en;q=0.9",
}


def fetch(url: str, attempts: int = 4) -> str:
    for attempt in range(attempts):
        try:
            response = requests.get(url, proxies=proxies, headers=headers, timeout=30)
            if response.status_code == 200:
                return response.text
        except requests.RequestException:
            pass
        # exponential backoff with jitter; the next request gets a new IP
        time.sleep(2**attempt + random.random())
    raise RuntimeError(f"Failed after {attempts} attempts: {url}")


print(fetch("https://api.ipify.org"))

Scraping responsiblyCopy Anchor Link

• Collect only public data you have a lawful basis to use.
• Respect robots.txt and rate limits, and identify your scraper where appropriate.
• Do not use proxies to log in to accounts you do not own or to bypass paywalls.
