Json data fetch with file_get_contents missing and incorrect every time

I want to extract data from the api I wrote with file_get_contents and save it to the database. But every time I get different results. When I enter the json page from the browser, the data comes complete every time. But when I do it this way, sometimes 5 sometimes 20 data is brought and recorded in the database. This is completely random. I think I'm going crazy.

data pulling function

function fetchData($id){
          
$url = "https://mywebsite.com/getcomments/".$id."/100";

$myJsonData = file_get_contents($url);
$json = json_decode($myJsonData);
  return $json;

  }

database registration section

        $json_data = fetchData($td);

        $yorumlar = $json_data->result;
       
                    foreach($yorumlar as $key => $data)
            {
     $satir = $data->review;
     $name = $data->name;
       $data = array(
                    'comment_post_ID' => $post_id,
                    'comment_author' => $result,
                    'comment_author_email' => 'tester@testerz.com',
                    'comment_content' => $satir,
                    'user_id' => 3,
                    'comment_meta' => array('ratingValue', $data->rating),
                    'comment_approved' => 1,
                    'comment_type' => 'custom-comment-class'
                );
                
                 wp_insert_comment($data);
            }    

Is file_get_contents not working properly? Or I am not sure if I can't use the imported data properly. But isn't it weird that sometimes it returns 5 sometimes 20 sometimes 14 data?
