    AgentQL query to scrape the url.

    Here is a guide on AgentQL query syntax:

    Enclose all AgentQL query terms within curly braces `{}`. The following query structure isn't valid because the term "social_media_links" is wrongly enclosed within parenthesis `()`.

    ```
    ( # Should be {
        social_media_links(The icons that lead to Facebook, Snapchat, etc.)[]
    ) # Should be }
    ```

    The following query is also invalid since its missing the curly braces `{}`

    ```
    # should include {
    social_media_links(The icons that lead to Facebook, Snapchat, etc.)[]
    # should include }
    ```

    You can't include new lines in your semantic context. The following query structure isn't valid because the semantic context isn't contained within one line.

    ```
    {
        social_media_links(The icons that lead
            to Facebook, Snapchat, etc.)[]
    }
    ```
