Custom REST Endpoint | WordPress.org

hey !
I’m having a cache with the REST API.
Everything is working as expected, but the moment I change any value it takes up to 30sec / 1 min.

Try with set up headers,etc, but ain’t workin.

This is the code that I’m running.

add_action('rest_api_init', 'get_wp_page_fn2' );

function get_wp_page_fn2(){
    register_rest_route( '/wp/v2/tf_api/' ,'get_wp_page2', 
        array(
            'methods'  =>'GET',
            'callback' => 'get_wp_page_callback2',
        ) 
    );
}

function get_wp_page_callback2( $request) {
    $permalink = $request['permalink'];

    $data = array(
        $permalink,
        'is not updating', 
        get_template_directory_uri().'/home.112312323.js',
        'maybe not'
    );
    // Create the response object
    $response = new WP_REST_Response( $data );
    $response->header( 'Pragma', 'no-cache' );
    $response->header( 'Cache-Control', 'no-store, no-cache, must-revalidate' );
    $response->header( 'Expires',gmdate( 'D, d M Y H:i:s \G\M\T', time() )); 
    $response->header( 'Last-Modified',gmdate( 'D, d M Y H:i:s \G\M\T', time() )); 
    wp_send_json($response);
}
