How to download the exchange rate from the Tinkoff website?

Question

Google Apps Script

It is required to load from the page https://www.tinkoff.ru/about/exchange/ the exchange rate of rubles for dollars (about 140 now) in google tables.
As far as I understand, this can be done using IMPORTXML(" https://www.tinkoff.ru/about/exchange "; "/html/body/div[1]/div/div/div[2]/div/div[ 3]/div[2]/div[3]")
But for some reason the formula doesn't produce anything.

Answer 1

It is simply not in the original HTML, it is obtained by the script
Look towards this request:

fetch("https://api.tinkoff.ru/v1/currency_rates?from=USD&to=RUB", {
  "headers": {
    "accept": "*/*",
    "accept-language": "ru-RU,ru;q=0.9,en-US;q=0.8,en;q=0.7",
    "content-type": "application/x-www-form-urlencoded",
    "sec-ch-ua": "\" Not A;Brand\";v=\"99\", \"Chromium\";v=\"99\", \"Google Chrome\";v=\"99\"",
    "sec-ch-ua-mobile": "?0",
    "sec-ch-ua-platform": "\"Windows\"",
    "sec-fetch-dest": "empty",
    "sec-fetch-mode": "cors",
    "sec-fetch-site": "same-site"
  },
  "referrer": "https://www.tinkoff.ru/",
  "referrerPolicy": "strict-origin-when-cross-origin",
  "body": null,
  "method": "GET",
  "mode": "cors",
  "credentials": "omit"
});
