Here's an example implementation using jQuery:

$(document).ready(function() {
  // Function to update the JSON-LD script
  function updateJSONLD(data) {
    var script = $('script[type="application/ld+json"]');

    // Check if the script tag exists
    if (script.length === 0) {
      // If not, create a new script tag and append it to the head
      script = $('<script>').attr('type', 'application/ld+json').text(JSON.stringify(data));
      $('head').append(script);
    } else {
      // If it exists, update its content
      script.text(JSON.stringify(data));
    }
  }

  // AJAX request to retrieve the JSON data
  $.ajax({
    url: "your_api_endpoint",
    method: "GET",
    dataType: "json",
    success: function(data) {
      // Update the JSON-LD script with the retrieved data
      updateJSONLD(data);
    },
    error: function(xhr, status, error) {
      // Handle the error
    }
  });
});

In this example, the updateJSONLD() function is used to update the content of the JSON-LD script. It checks if the script tag exists on the page and either creates a new script tag or updates its content. The AJAX request is made to retrieve the JSON data, and the updateJSONLD() function is called in the success callback to update the script with the retrieved data.

You can adjust this example to fit your specific needs, such as handling errors or triggering the update at different events.
