# Has Url

Automatically detect URLs in AI outputs. Ensure link presence is flagged and handled correctly.

**Objective**\
This metric checks if the text contains a valid URL, ensuring proper handling of web links.

**Interpretation**\
A higher score indicates the presence of a valid URL in the response. A lower (or zero) score indicates no valid URL was found.

**Code Execution**

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

**Example**

* **Prompt**: “Can you provide a link to your product page?”
* **Context**: “We only allow official links.”
* **Response**: “Visit <http://example.com> for more details.”
* **Metric Output**: `{"score": 1, "reason": "Response contains a valid URL."}`
