# Live URL

**Objective**\
Verifies if URLs in the text are live and accessible, ensuring the validity of web links.

**Interpretation**\
A higher score indicates one or more URLs in the response are broken or inaccessible. A lower (or zero) score indicates all URLs are verified as live.

**Code Execution**

```python
metrics = [
    {
        "name": "Live Url",
        "config": {
            "model": "gpt-4o-mini",
            "provider": "openai"
        },
        "column_name": "your-column-identifier",
        "schema_mapping": schema_mapping
    }
]
```

**Example**

* **Prompt**: “Please provide a reliable source for this information.”
* **Context**: “Ensure any URLs are live and accessible.”
* **Response**: “You can check out <http://thisisnotavaliddomain.example.”>
* **Metric Output**: `{"score": 1, "reason": "The provided URL is not live or accessible."}`
