| Rate limiting | You manage it | Built-in, respectful |

| robots.txt compliance | Manual check | Automatic |

| Server overload risk | High if misconfigured | Cloud-distributed |

| IP reputation | Your IP gets flagged | Managed IP pool |

| Data extraction | Parse HTML yourself | AI-powered, structured |

With a web scraping API, you get clean, structured data without the legal and technical overhead of building and maintaining your own scraper infrastructure.

AI-Powered Extraction

WebPerception goes beyond basic scraping with AI extraction — tell it what data you need in plain language:

response = requests.post(
    "https://api.mantisapi.com/v1/extract",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    json={
        "url": "https://example.com/product/widget-pro",
        "prompt": "Extract the product name, price, and availability"
    }
)

# Returns structured JSON — no HTML parsing needed
# {"product_name": "Widget Pro", "price": "$49.99", "availability": "In Stock"}
