## Response Format

All tools return a standardized JSON response:

```json
{
  "success": true,
  "message": {
    // Tool-specific data here
  },
  "metadata": {
    "provider": "API name",
    "api_key_required": false
  }
}
```

## Tips & Best Practices

1. **Rate Limiting**: Be respectful of free APIs - don't make excessive requests
2. **Caching**: Cache results when possible to reduce API calls
3. **Error Handling**: Always check the `success` field in responses
4. **User Agent**: Tools use appropriate User-Agent headers for API compliance
