## Rate Limiting

API requests are rate-limited to prevent abuse:
- **Default limit:** 100 requests per minute
- **Burst limit:** 200 requests per minute

Rate limit headers are included in responses:
- `X-RateLimit-Limit`: Request limit per window
- `X-RateLimit-Remaining`: Remaining requests
- `X-RateLimit-Reset`: Time when limit resets

## Pagination

List endpoints support pagination with the following parameters:
- `page` (int, default: 1): Page number
- `limit` (int, default: 20, max: 100): Items per page

Pagination metadata is included in responses:
```json
{
  "data": [...],
  "total": 150,
  "page": 1,
  "limit": 20,
  "pages": 8
}
```

## Search and Filtering

Most list endpoints support search and filtering:
- `search` (string): Search in relevant fields
- `tag` (string): Filter by tags
- `status` (string): Filter by status (for tasks)
- `priority` (string): Filter by priority (for tasks)
- `type` (string): Filter by file type (for files)

## File Upload Limits

- **Maximum file size:** 100MB
- **Allowed file types:** Images, documents, archives
- **Storage location:** Configurable (local/cloud)

## Security Considerations

- All sensitive endpoints require JWT authentication
- Passwords are hashed using bcrypt
- File uploads are scanned for security threats
- CORS is configured for cross-origin requests
- Rate limiting prevents abuse
- Input validation prevents injection attacks
