# BigCodeBench/28

Implement a file **`solution.py`** that completes the function below. Keep the given name and signature; define `task_func` at module level.

Allowed libraries: `base64`, `requests`, `json`.

```python
import requests
import json
import base64

def task_func(data, url="http://your-api-url.com"):
    """
    Convert a Python dictionary into a JSON-formatted string, encode this string in base64 format,
    and send it as a 'payload' in a POST request to an API endpoint.
    
    Parameters:
    data (dict): The Python dictionary to encode and send.
    url (str, optional): The API endpoint URL. Defaults to "http://your-api-url.com".
    
    Returns:
    requests.Response: The response object received from the API endpoint after the POST request.
    
    Requirements:
    - requests
    - json
    - base64
    
    Example:
    >>> data = {'name': 'John', 'age': 30, 'city': 'New York'}
    >>> response = task_func(data, url="http://example-api-url.com")
    >>> print(response.status_code)
    200
