# API Error Handling

Implement robust error handling with standardized responses and proper logging.

## Standard Error Response Format

```json
{
  "error": {
    "code": "VALIDATION_ERROR",
    "message": "Invalid request parameters",
    "status": 400,
    "requestId": "req_abc123",
    "timestamp": "2025-01-15T10:30:00Z",
    "details": [
      { "field": "email", "message": "Invalid email format" }
    ]
  }
}
```

## Error Class (Node.js)

```javascript
class ApiError extends Error {
  constructor(code, message, status = 500, details = null) {
    super(message);
    this.code = code;
    this.status = status;
    this.details = details;
  }

  static badRequest(message, details) {
