# Valid URL

Automatically check if URLs generated by AI are valid. Reduce errors with automated guardrails.

**Objective**\
Checks if the text contains a valid URL format, ensuring proper web link handling.

**Interpretation**\
A higher score indicates the URL is invalid or malformed. A lower (or zero) score indicates the URL format is valid.

**Code Execution**

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

**Example**

* **Prompt**: “Provide the official website link.”
* **Context**: “Ensure the URL is correctly formatted.”
* **Response**: “wwwexamplecom”
* **Metric Output**: `{"score": 1, "reason": "Invalid URL format detected (missing protocol and dots)."}`
