General API utilities for Lidl Connect.

### make_api_request(url, data=None, method="POST") → Union[Dict[str, Any], str]

Make a generic API request to Lidl Connect.

```python
response = client.make_api_request(
    "https://selfcare.lidl-connect.at/customer/some-endpoint", 
    data={"key": "value"}
)
```

## Caching

The library has a time-based cache for API requests to reduce load and improve performance.

Key caching parameters:
- Usage data: 5 seconds TTL
- User data: 30 seconds TTL
- Invoices and vouchers: 30 seconds TTL
- Tariffs: 60 seconds TTL

The cache is implemented using the `ttl_cache` decorator in helpers.py.
The user data cache is cleared automatically when a credit top-up occurs.

## Error Handling

Most methods raise `ValueError` exceptions when:
- Not logged in or missing CSRF token
- API requests fail
- Required data is missing

All public properties safely handle exceptions internally and return None when errors occur, ensuring your application doesn't crash.

Example of error handling:

```python
try:
    client = LidlConnect(identifier="069012345678", puk="12345678")
    if not client.initialize():
        print("Failed to initialize client")
        exit(1)
        
    # Your code here
    
except ValueError as e:
    print(f"API error: {e}")
except Exception as e:
    print(f"Unexpected error: {e}")
finally:
    if hasattr(client, 'logout') and client.logged_in:
        client.logout()
```
