Web Scraping API for Python
Use AlterLab's web scraping API with Python to extract structured data from any website. The REST API works with any HTTP library — requests, httpx, aiohttp — and our official SDK provides async/sync helpers with automatic retries.
Quick Start
import requests
response = requests.post(
"https://alterlab.io/api/v1/scrape",
headers={"X-API-Key": "YOUR_API_KEY"},
json={"url": "https://example.com"}
)
data = response.json()
print(data["content"])Need an API key? — no credit card required.
How It Works

The API returns clean JSON with page content, metadata, and any structured fields you requested via an extraction schema.
Use in your project
Integrate the response into your Python application, database, or workflow. No scraper maintenance required.
