# How to Handle Website Challenges Automatically

Many websites present challenge pages to verify that visitors are real users before delivering content. Standard HTTP scrapers receive the challenge page instead of the data — requiring a full browser environment with challenge resolution capability to proceed.

## Step-by-Step Guide

1

### Identify the challenge type

Common challenges include JavaScript verification pages and browser integrity checks. If your scraper returns a page asking to 'verify you are human', a compatibility-capable browser environment is needed.

2

### Use AlterLab's automatic compatibility tier

Send your request to AlterLab with the appropriate tier parameter. The API automatically selects a browser environment capable of resolving the challenge on the target site.

3

### Verify the response contains your data

Check the returned HTML for your target content. If the challenge was resolved, you will receive the actual page content rather than the challenge page.

## Code Example

Python

```
import requests

response = requests.post(
    "https://alterlab.io/api/v1/scrape",
    headers={"X-API-Key": "YOUR_API_KEY", "Content-Type": "application/json"},
    json={
        "url": "https://example.com/protected-page",
        "render_js": "auto",
        # AlterLab auto-escalates to the appropriate compatibility tier
    },
)

data = response.json()
print(f"Status: {data['status_code']}")
print(f"HTML length: {len(data.get('html', ''))}")
```

Replace `YOUR_API_KEY` with your key from the . No credit card required.
