i find way to manage nested resource

first go to this link
    https://restfulapi.net/resource-naming/
to understand restful api then decide what you want to follow . i think its up to you
which way to go no nested vs nested
here`s my code  

PHP Code:

$routes->group('api', ['namespace' => 'App\Controllers\Api'], function ($routes) {
$routes->get('x/new', 'X::new');
    $routes->post('x/create', 'X::create');
    $routes->post('x', 'X::create');  // alias
    $routes->get('x', 'X::index');
    $routes->get('x/show/(:segment)', 'X::show/$1');
    $routes->get('x/(:segment)', 'X::show/$1');  // alias
    $routes->get('x/edit/(:segment)', 'X::edit/$1');
    $routes->post('x/update/(:segment)', 'X::update/$1');
    $routes->get('x/remove/(:segment)', 'X::remove/$1');
    $routes->post('x/delete/(:segment)', 'X::update/$1');

    $routes->get('x/(:segment)/y/new', 'Y::new/$1');
    $routes->post('x/(:segment)/y', 'Y::create/$1');
    $routes->get('x/(:segment)/y', 'Y::index/$1');
    $routes->get('x/(:segment)/y/(:segment)', 'Y::show/$1/$1');
    $routes->get('x/(:segment)/y/(:segment)/edit', 'Y::edit/$1/$1');
    $routes->put('x/(:segment)/y/(:segment)', 'Y::update/$1/$1');
    $routes->patch('x/(:segment)/y/(:segment)', 'Y::update/$1/$1');
    $routes->delete('x/(:segment)/y/(:segment)', 'Y::delete/$1/$1');
});

I think with new define:
- only one url: yoursite.com/api/v1
- only one POST request
- define data post:
- ------ type [get, put, patch, list, sort, add, delete,... anything you want]
- ------ data,...
On your api controller handle, map type with function, then process and return,...
