Return HTML instead of JSON

Hello, I have a little problem, I make a GET request into a website (not api) but he return me a JSON, but I would like to parse the HTML to get the value directly, do you have any idea?

  url = $"<input.DATA>"
  customHeaders = {("Accept", "*/*"), ("Accept-Encoding", "gzip, deflate, br"), ("Accept-Language", "en"), ("Connection", "keep-alive"), ("Cookie", "cookieconsent=true"), ("Host", "[]("), ("Referer", "https://[[](]("), ("Sec-Fetch-Dest", "empty"), ("Sec-Fetch-Mode", "cors"), ("Sec-Fetch-Site", "same-origin"), ("Sec-GPC", "1"), ("User-Agent", "<randomUserAgent>")}
Response code: 200

Received Headers:

Date: Sat, 06 Aug 2022 15:51:23 GMT
Server: Kestrel
Transfer-Encoding: chunked
Strict-Transport-Security: max-age=2592000
Content-Type: application/json; charset=utf-8
Content-Length: 25586

If the ‘html’ you are referring to is the code that you see from inspecting the page on a browser, then you need to the corresponding request which returns that document, if there is any.
Otherwise you might have to use puppeteer
