3rd party Api returns error as html

<html><head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<title>500 Server Error</title>
</head>
<body text=#000000 bgcolor=#ffffff>
<h1>Error: Server Error</h1>
<h2>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. </h2>
<p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. .</p>
</body></html>

How can I use Ruby(Rails) to convert this message so that it would display on the page not the html code coming from the API, but the text contained in the message.
I'm new, so I would be grateful for a detailed answer)

require 'nokogiri'

api_body_result = <<-HTML

    <meta http-equiv="content-type" content="text/html;charset=utf-8">
    <title>500 Server Error</title>
  </head>
<body text=#000000 bgcolor=#ffffff>
  <h1>Error: Server Error</h1>
  <h2>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. </h2>
  <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. .</p>
  </body>
</html>
HTML

doc = Nokogiri::HTML api_body_result

# source html inner text
text = doc.text

# or

# html title
title = doc.title

# html body
element = doc.at_css 'body'
body = element.text
