Technical Questions

We provide several options for JavaScript-heavy sites:
  1. Wait Until Options: 
    {
  "wait_until": "networkidle0"  // Wait for network to be idle
}
  2. JavaScript Execution: 
    {
  "javascript": true,  // Enable JavaScript execution
  "wait_time": 5000   // Wait 5 seconds after load
}
  3. Custom Triggers: 
    {
  "wait_for": ".dynamic-content",  // Wait for element
  "timeout": 10000                 // Max wait time
}
Rate limits vary by plan: - Free: 60 requests/minute - Developer: 300 requests/minute - Business: 1,000 requests/minute - Enterprise: Custom limits We provide rate limit info in response headers: http X-RateLimit-Limit: 60 X-RateLimit-Remaining: 45 X-RateLimit-Reset: 1625097600
Implement exponential backoff for rate-limited requests.
We support multiple authentication methods for target websites:
  1. Cookie-based: 
    {
  "headers": {
    "Cookie": "session=abc123"
  }
}
  2. Header-based: 
    {
  "headers": {
    "Authorization": "Bearer token123"
  }
}
  3. Form Login: 
    {
  "authentication": {
    "type": "form",
    "loginUrl": "https://example.com/login",
    "username": "user",
    "password": "pass"
  }
}
We employ several strategies to handle anti-bot measures:
  1. Rotating IP addresses
  2. Browser fingerprint randomization
  3. Human-like behavior patterns
  4. Automatic CAPTCHA solving (Enterprise plans)
Some websites may explicitly prohibit scraping. Always check terms of service.

Troubleshooting

Common error codes and solutions:
  • 401: Invalid API key
  • 403: Permission denied
  • 429: Rate limit exceeded
  • 500: Server error
  • 504: Timeout
See our Error Handling guide for details.
Timeouts can occur for several reasons: 1. Slow Website: - Increase timeout: "timeout": 30000 - Use wait_until: "networkidle0" 2. Complex JavaScript: - Enable JS: "javascript": true - Add wait time: "wait_time": 5000 3. Large Pages: - Use selective extraction - Implement pagination
Try these troubleshooting steps: 1. Check Selectors: - Use browser dev tools to verify - Try multiple selector options 2. JavaScript Content: - Enable JS execution - Add appropriate wait conditions 3. Dynamic Content: - Use wait_for with specific elements - Implement retry logic
If you’re getting blocked:
  1. Implement Delays: 
    {
  "delay": {
    "min": 2000,
    "max": 5000
  }
}
  2. Rotate User Agents: 
    {
  "headers": {
    "User-Agent": "custom-agent"
  }
}
  3. Use Enterprise Features:
    • Residential proxies
    • IP rotation
    • Custom headers
