Bot detection errors 503

[FrasIrfan]

Why do I get bot detection errors 503 when fetching data from websites like Amazon, Zillow

Is there any way i can bypass them using Scrapegraph (already using)

Hi @FrasIrfan! I'm Dosu and I’m helping the Scrapegraph-ai team.

Sites like Amazon and Zillow use advanced anti-bot systems that often return HTTP 503 errors when they detect scraping activity. This can happen due to things like repeated requests from the same IP, use of headless browsers, or missing browser fingerprints.

ScrapeGraphAI has several features that can help you bypass or reduce these errors:

• You can rotate proxies using ScrapeGraphAI’s built-in proxy rotation utility, which lets you search for and use proxies based on anonymity, country, and security. This helps distribute your requests and avoid IP bans or rate limits [proxy_rotation.py].
• The FetchNode and ChromiumLoader support proxy configuration, headless/visible browser modes, retry logic, and stealth techniques like undetected_chromedriver and Malenia for Playwright. Disabling headless mode (with a virtual display if needed) can help bypass some anti-bot protections [fetch_node.py] [chromium.py].
• You can integrate with external proxy services like Scrape.do for residential/mobile proxies and geo-targeting, which are harder for anti-bot systems to block [scrape_do.py].

Best practices: rotate proxies, try running browsers in non-headless mode (with xvfb or pyvirtualdisplay if you’re on a server), and mimic human browsing behavior as much as possible. ScrapeGraphAI does not have built-in user-agent rotation or CAPTCHA solving, so you’ll need to handle those externally if required.

If you want a code example or config snippet for any of these features, let me know!

To reply, just mention @dosu.
