function prefix_get_endpoint_phrase() {
// rest_ensure_response() wraps the data we want to return into a WP_REST_Response, and ensures it will be properly returned.
$url1 = 'https://forblitz.ru/wp-json/wp/v2/posts?sticky=true'; // path to your JSON file
$url2 = 'https://forblitz.ru/wp-json/wp/v2/posts?per_page=30&categories_exclude=1'; // path to your JSON file
$json1 = file_get_contents($url1);
$json2 = file_get_contents($url2);
$my_array1 = json_decode($json1, true);
$my_array2 = json_decode($json2, true);
$res = array_merge($my_array1, $my_array2);
return $res;
}
