XMLHttpRequest error and isAjax not work

i am trying to make the following request with ajax but i get an error - 
XMLHttpRequest cannot load https://api.domain.com/view?id=1&csrf_na...0524468477 due to access control checks.

my script:

Code:

$.ajax({
    url:'https://api.domain.com/view',
    method: 'get',
data: {'id':'<?= session()->get('id') ?>','<?= csrf_token() ?>':'<?= csrf_hash() ?>'},
headers: {'X-Requested-With': 'XMLHttpRequest'},
dataType: "json",
cache: false,
success: function (data) {

url site: https://my.domain.com
controller:

PHP Code:

public function view() {

if ($this->request->isAJAX())        { 

 /* my code */

}

} 


i also think the isAjax check doesn't work either
