      "Content-Type": "application/json",
      "Authorization": "Bearer YOUR_API_KEY"
    }
  }
}
```

## 📖 Usage Examples

### Basic Website Scraping
```python
from webscraper import WebScraper

scraper = WebScraper('config.json')
result = scraper.scrape_url('https://example.com')

if result['success']:
    data = result['data']
    print(f"Title: {data['title']}")
    print(f"Content: {data['text_content'][:500]}...")
else:
    print(f"Failed: {result['reason']}")

scraper.close()
```

### Nested Link Crawling
```python
result = scraper.scrape_url(
    'https://example.com',
    nested=True  # Enable nested crawling
)

if result['success'] and 'nested_pages' in result['data']:
    for page in result['data']['nested_pages']:
        print(f"Found page: {page['url']}")
        if page['success']:
            print(f"  Title: {page['data']['title']}")
```

### File Extraction
```python
result = scraper.scrape_url(
    'https://example.com/documents',
    download=True  # Enable file downloading
)

if result['success'] and 'extracted_files' in result['data']:
    for file_data in result['data']['extracted_files']:
        print(f"Extracted: {file_data['url']}")
        print(f"Type: {file_data['data']['file_type']}")
        print(f"Content: {file_data['data']['content'][:200]}...")
```

### Handling Robots.txt Restrictions
```python
# Respect robots.txt (default)
result = scraper.scrape_url('https://example.com')

# User claims site ownership (with disclaimer)
result = scraper.scrape_url('https://example.com', user_owns_site=True)

# Brute force mode (ignore robots.txt - use responsibly)
result = scraper.scrape_url('https://example.com', brute_force=True)
```

### Quick Scraping Function
```python
from webscraper import quick_scrape

result = quick_scrape(
    url='https://example.com',
    nested=True,
    download=False
)
```

## 🤖 LLM Integration

The scraper can use AI to interpret ambiguous robots.txt files. Supported providers:

### OpenAI
```json
{
  "llm": {
    "provider": "openai",
    "model": "gpt-3.5-turbo",
    "api_key": "your-openai-api-key"
  }
}
```

### Anthropic Claude
```json
{
  "llm": {
    "provider": "anthropic",
    "model": "claude-3-sonnet-20240229",
    "api_key": "your-anthropic-api-key"
  }
}
```

### Custom Provider
```json
{
  "llm": {
    "provider": "custom",
    "model": "your-model",
    "api_key": "your-api-key",
    "base_url": "https://your-llm-endpoint.com"
  }
}
```

## 🔧 CLI Commands

### Scraping
```bash
# Basic scraping
respectscraper scrape https://example.com

# Advanced options
respectscraper scrape https://example.com \
  --nested \
  --download \
  --config custom_config.json \
  --output results.json \
  --pretty

# Ignore robots.txt
respectscraper scrape https://example.com --brute-force

# User owns site
respectscraper scrape https://example.com --user-owns-site

# Bypass SSL certificate verification (for problematic sites)
respectscraper scrape https://example.com --ssl-bypass
```

### Configuration
```bash
# Create default config
respectscraper config --create

# Create config at custom path
respectscraper config --create --path my_config.json

# Validate existing config
respectscraper config --validate --path config.json
```

### Validation and Info
```bash
# Validate installation
respectscraper validate

# Show package info
respectscraper info
```

## 🔒 Handling SSL Certificate Issues

Some websites have SSL certificate problems that prevent scraping. RespectScraper provides several ways to handle this:

### Quick Solution (CLI)
```bash
# Bypass SSL verification for a single scrape
respectscraper scrape https://problematic-site.com --ssl-bypass
```

### Configuration Solution
Edit your `config.json`:
```json
{
  "general": {
    "verify_ssl": false,
    "allow_ssl_bypass": true
  }
}
```

### Python API Solution
```python
scraper = WebScraper('config.json')
# Temporarily disable SSL verification
scraper.session.verify = False
result = scraper.scrape_url('https://problematic-site.com')
```

### ⚠️ Security Warning
Disabling SSL verification reduces security. Only use this for:
- Trusted websites with known certificate issues
- Internal/development servers
- When you understand the security implications

## 📁 File Extraction Support

The scraper can extract content from various file types:

- **PDF**: Text extraction from all pages with metadata
- **Excel**: Cell data from all sheets with sheet names
- **Word**: Text and tables with document metadata
- **Text**: Auto-encoding detection for text files

## 🛡️ Ethical Usage

This tool is designed for **responsible web scraping**:

### ✅ Good Practices
- Always respect robots.txt files
- Use appropriate delays between requests
- Don't overload servers with too many concurrent requests
- Only scrape public, non-copyrighted content
- Respect terms of service
- Use the `user_owns_site` flag only for sites you actually own

### ❌ Don't Use For
- Scraping content behind login walls without permission
- Violating website terms of service
- Overloading servers with aggressive scraping
- Collecting personal or private data
- Copyright infringement

### Robots.txt Override Options

The scraper provides override options but use them responsibly:

1. **User Owns Site**: Use `user_owns_site=True` only if you actually own the website
2. **Brute Force**: Use `brute_force=True` only with explicit permission or for testing
3. **Both options show disclaimers about responsible usage**

## 🔍 API Integration

Send scraped data automatically to your API:

```python
# Configure in config.json
{
  "api": {
    "enabled": true,
    "endpoint": "https://your-api.com/scraped-data",
    "method": "POST",
    "headers": {
      "Authorization": "Bearer YOUR_TOKEN"
    }
  }
}
```

The scraper will automatically send structured data:
```json
{
  "timestamp": "2024-01-01T12:00:00Z",
  "data": {
    "url": "https://example.com",
    "title": "Example Title",
    "content": "Scraped content...",
    "word_count": 500,
    "nested_pages": [...],
    "extracted_files": [...]
  }
}
```

## 🧪 Testing Installation

```bash
# Validate installation
respectscraper validate

# Test with a simple page
respectscraper scrape https://httpbin.org/html --pretty
```

## 📚 Advanced Usage

### Custom User Agent
```python
# Modify config.json
{
  "general": {
    "user_agent": "MyRespectfulBot/1.0 (+https://mysite.com/bot-info)"
  }
}
```

### Rate Limiting Configuration
```python
{
  "crawling": {
    "delay_between_requests": 2.0,  # 2 seconds between requests
    "max_concurrent_requests": 3    # Max 3 concurrent requests
  }
}
```

### File Size Limits
```python
{
  "file_extraction": {
    "max_file_size_mb": 100,  # Don't download files larger than 100MB
    "supported_extensions": [".pdf", ".xlsx", ".docx", ".txt"]
  }
}
```

## 🐛 Troubleshooting

### Common Issues

1. **"Configuration file not found"**
   ```bash
   respectscraper config --create
   ```

2. **"LLM API key not configured"**
   - Edit `config.json` and add your API key in the `llm` section

3. **"Robots.txt blocks scraping"**
   - Check the robots.txt file manually
   - Use `--user-owns-site` if you own the site
   - Use `--brute-force` only if you have permission

4. **"SSL Certificate verification failed"**
   - Try with SSL bypass: `respectscraper scrape URL --ssl-bypass`
   - Or edit config.json: `"allow_ssl_bypass": true, "verify_ssl": false`
   - ⚠️ **Warning**: Only bypass SSL for trusted sites

5. **"Rate limited"**
   - Increase `delay_between_requests` in config
   - Reduce `max_concurrent_requests`

6. **"File extraction failed"**
   - Check if the file type is supported
   - Verify file isn't corrupted
   - Check file size limits

### Debug Mode
```python
# Enable debug logging
{
  "logging": {
    "level": "DEBUG",
    "file": "debug.log"
  }
}
```
