    When we call the rest API of SharePoint online in SharePoint 2013, we need to perform identity authentication. We could use Microsoft Authentication Library (MSAL).
    Official demo:Tutorial: Sign in users and call the Microsoft Graph API from a JavaScript single-page application (SPA)
    Similar issue for your reference:
    Unauthorized request in Sharepoint API with MSAL token
    Access SharePoint Online "_api/web/..." api using the MSAL library

    Or you could try to copy the list from online to 2013, and then request this rest API in 2013 directly.
