appscript urlfetch responds with missing auth token even though api doesnt require auth

Question

Im making a url fetch api call from google appscript nhtsa which according to their documentation doesnt require any authentication yet my response I am getting is missing authentication token but I can enter the same decoded url into browser and and access the json data fine. Makes no sense to me. My code is below. ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

    function openRecll() {
    var make = ("dodge"); // set variables for vehicle to but searched
    var model = ("charger");
    var year = ("2021");


    // set variables for what needs encoded parts of url that need encoding
    var makeenc = ("?make=");
    var modelsenc = ("&model=");
    var yearsenc = ("&modelYear=");

   //encode string
   estring = encodeURIComponent(makesenc+make+modelsenc+model+yearsenc+year);

  var url = ("api.nhtsa.gov/recalls/recallsByVehicle"+estring);

  Logger.log (url);

  response = UrlFetchApp.fetch(url);
}
