WebPerception API vs ScrapingBee

The Key Difference: AI-Powered Extraction

ScrapingBee returns raw HTML. That means you still need to write CSS selectors, handle edge cases, and parse messy markup into usable data. When a site changes its layout, your selectors break.

WebPerception API uses AI to understand the page and extract structured data automatically. Tell it what you want — product names, prices, contact info — and get clean JSON back. No selectors. No maintenance.

ScrapingBee: Manual Extraction

# ScrapingBee — returns raw HTML, you parse it yourself
import requests
from bs4 import BeautifulSoup

response = requests.get("https://app.scrapingbee.com/api/v1/", params={
    "api_key": "YOUR_KEY",
    "url": "https://example.com/product",
    "render_js": "true"
})

# Now you need to manually parse the HTML
soup = BeautifulSoup(response.text, "html.parser")
title = soup.select_one(".product-title").text  # Breaks when class changes
price = soup.select_one(".price-value").text     # Breaks when layout changes
# ... more fragile selectors

WebPerception API: AI Extraction

# WebPerception API — structured data, no selectors needed
import requests

response = requests.post("https://api.mantisapi.com/v1/extract", json={
    "url": "https://example.com/product",
    "schema": {
        "product_name": "string",
        "price": "number",
        "currency": "string",
        "in_stock": "boolean"
    }
})

data = response.json()
# {"product_name": "Widget Pro", "price": 49.99, "currency": "USD", "in_stock": true}
# Works even when the site redesigns

Pricing: WebPerception Wins

At the entry level, WebPerception gives you 5× more calls at 60% of the price — and includes AI extraction that ScrapingBee doesn't offer at any tier.

When to Choose Each

Choose WebPerception API if:

• You're building AI agents that need web data
