    ping_status: 'open',
    sticky: false,
    template: '',
    format: 'standard',
    meta: [],

      curies: [Array]
    _embedded: {
      author: [Array],
      'wp:term': [Array]

But as you can see there is no featured_media. Do I have a misunderstanding about featured_media? I made my post with an image like you can see in content.rendered

    Well, I don't think the post actually has a featured image. The one in the content.rendered is an image added using the Image block. You set the featured image via the "Set featured image" link in the "Featured Image" meta box, even when using the block editor.

  • @evgenifotia, I'm glad the comment helped. And just to be clear, this is what I meant, which is for the block editor. :)

You don't set featured image for your post ,so return 0 in feature image obj. after set it you can use featured image obj.

for example: I wrote this with PHP, you can upload this to another host and display the images of the WordPress website that you specified in the URL variable on those hosts.

$url = 'url of your wordpress website';
function Json_Data_Decoder($query){     
    global $url;
    $json = file_get_contents($url.'/wp-json/wp/v2/'. $query);
    $data = json_decode($json);
    return $data;
function Get_Media($post_media){
    global $url;
    $json = file_get_contents($url.'/wp-json/wp/v2/media?include='.$post_media);
    $medias = json_decode($json);
    $featured_image = $medias[0]->media_details->sizes->medium->source_url;
    return $featured_image;

$posts = Json_Data_Decoder('posts');
foreach ($posts as $post){
    // get media 
    $post_media = $post->featured_media;
    $featured_image = Get_media($post_media);
    '<article class="post image">
            <img src="'.
                $featured_image .
  • In WordPress's REST API, the featured_media should be automatically set, without needing a plugin. It'll return the featured image's ID or 0 if there's not a featured image.
