Change title of page dynamically in page

I have an page (with snippet code and short code and manual php code) and it call a REST API and base Of response, I want change tag title of this page (Not in database).and it was change every call.

i try do :

in snippet code:

$GLOBALS['MyTitle'] = $response-> title;

in function:

function change_title($title) {
 
        $variable = $GLOBALS['MyTitle'];
      
        if (!empty($variable)) 
        {
             $title = $variable;
        } 
    
    return $title;
}
add_filter('pre_get_document_title', 'change_title',500);

but it was empty every time because the function section run sooner then snippet code(Api Call).

WordPress has not any function for change title tag text? like wp_set_title('my title') to use without add_filter?

Changing title of the page dynamically by applying the filter the hook used for the filter is document_title_parts. Here is the official wordpress documentation link and below is the example. In this example i have used get method for API.

add_filter( 'document_title_parts', 'function_to_dynamic_title');
function function_to_dynamic_title( $title_parts_array ) {

        $request = wp_remote_get( 'https://dummyjson.com/products/1' );

        if( is_wp_error( $request ) ) {
            return $data;
        }

        $body = wp_remote_retrieve_body( $request );

        $data = json_decode( $body );

        $title_parts_array['title'] = $data->title;
    
    return $title_parts_array;
}

In WordPress, we have an action to change the title programmatically.

add_filter('the_title','your_callback_function');
function your_callback_function($data)
{
  global $post;
  // add your condition according to page 
  return 'Desired Title'. $post->ID;
}
