## Usage

### Scrape Website

```bash

  --pages 10
```

### Extract from API

```

# Parse CSV
hermes scrape file data.csv --format json

# Parse Excel
hermes scrape file report.xlsx --sheet "Sales"

# Parse PDF

```

## Configuration

```yaml
# scraper-config.yml

  delay: 1000  # ms between requests
  retries: 3
  timeout: 30
  
anti_bot:
  rotate_user_agent: true
  use_proxy: false
  bypass_cloudflare: true
  
output:

```

hermes scrape --selector ".product .title" --attr text
hermes scrape --selector "img.product" --attr src
```

## Pitfalls

1. **Legal Issues** — Check robots.txt and terms of service
2. **Rate Limits** — Don't overload servers
3. **Data Quality** — Verify extracted data accuracy
4. **Anti-bot** — Some sites block scrapers
