Good day to all ! The essence of the question is - how can I display on the site how much money was invested in a smart contract (ETH)? You can just give a link to the normal documentation in Russian where everything is clear, I implement everything in PHP!

<?php
$id = $_POST['id'];
// Создаем поток
$opts = array(
  'http'=>array(
    'method'=>"GET",
    'header'=>"Accept-language: en\r\n" .
              "Cookie: foo=bar\r\n"

// Открываем файл с помощью установленных выше HTTP-заголовков
$file = file_get_contents(' http://api.ethplorer.io/getAddressInfo/0xAbbc9BD37912762543BF1cae18bB7FfC25f34e36', false, $context);
