show error messages from an api in laravel blade

I'm starting to create a rest API with Laravel, which I have a question about since before when I did the validations in the controller, I sent it like this

    $rules = [
        'receptor' => 'required',
        'accion' => 'required',
        'state' => 'required',
        'fech_ini' => 'required',
        'fech_fin' => 'required',
    ];
    $message = [
        'receptor.required' => 'Receiver is Required',
        'accion.required' => 'Acción is Required',
        'state.required' => 'State is Required',
        'fech_ini.required' => 'Start Date is Required',
        'fech_fin.required' => 'End Date is Required',
    ];
    $validator = Validator::make($request->all(), $rules,$message);
    if($validator->fails()):
        return back()->withErrors($validator)->with('message','An error has occurred:')->with('typealert','danger')->withInput();
    else:
       //save
    endif;

and in my template blade it showed it like this

 <div class="social_media">
  @if (Session::has('message'))
    <div class="container mt-3">
      <div class="alert alert-{{ Session::get('typealert') }}" style="display:none;text-align: left;">
        {{ Session::get('message') }}
        @if ($errors->any())
          <ul>
            @foreach ($errors->all() as $error)
              <li>{{ $error }}</li>
            @endforeach
          </ul>
        @endif
        <script>
          $('.alert').slideDown();
          setTimeout(function(){ $('.alert').slideUp(); }, 10000)
        </script>
      </div>
    </div>
  @endif
</div>

but when making an api it is done differently since the error is sent by a json and in this way I did not get to the answer of how to show the messages on the blade since when consuming the Session api it does not work for me on the blade

$rules = [
    'receptor' => 'required',
    'accion' => 'required',
    'state' => 'required',
    'fech_ini' => 'required',
    'fech_fin' => 'required',
];
$message = [
    'receptor.required' => 'Receiver is Required',
    'accion.required' => 'Acción is Required',
    'state.required' => 'State is Required',
    'fech_ini.required' => 'Start Date is Required',
    'fech_fin.required' => 'End Date is Required',
];
$validator = Validator::make($request->all(), $rules,$message);
if($validator->fails()):
    return response()->json([
      'validator'=> $validator,
      'message'=> 'An error has occurred',
      'typealert' => 'danger',
    ]);
else:
   //save
endif;
