How to insert php code into the page in october CMS?

Question

OctoberCMS

There is a site on october.cms with one single page default.html
I know that in the "code" section I need to write php somehow sideways so that it works and displays the result with a tag like {{blabla} } But I'm so stupid that I don't know how it's right do. I ask for your help!

Here is the php code

<?php
$curl = curl_init();
curl_setopt_array($curl, array(
  CURLOPT_URL => "https://coingecko.p.rapidapi.com/exchanges/bamboo_relay/tickers",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "GET",
  CURLOPT_HTTPHEADER => array(
    "x-rapidapi-host: coingecko.p.rapidapi.com",
    "x-rapidapi-key: 6ffd1d2182msh846abeb6f107c2cp15e4c8jsn66196e744cac"
  ),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
function print_arr($arr){
  echo '<pre> ' . print_r($arr, true) . ' </pre>';
}

$infa = json_decode($response, true);

the code is put into the onStart() function, and what needs to be displayed is assigned to some $this field and then displayed in the markup. Better, of course, not as in the spaghetti given in the question, but to collect a normal array with data and walk through it in the output using the Twig loop.
