    "message": "Invalid input data",
    "details": {
      "field": "email",

    }
  }
}
```

### Common Error Codes

- `NOT_FOUND`: Resource not found
- `VALIDATION_ERROR`: Invalid input data
- `RATE_LIMITED`: Too many requests

## 📝 Rate Limiting

API endpoints are rate limited to prevent abuse:

- **Authentication**: 5 requests per minute
- **Content Creation**: 10 requests per minute
- **Search**: 30 requests per minute
- **General**: 100 requests per minute

Rate limit headers are included in responses:
```
X-RateLimit-Limit: 100
X-RateLimit-Remaining: 95
X-RateLimit-Reset: 1645123200
```
