Is there other options for Yahoo's YQL for extracting HTML from other websites

Question

In my application I used Yahoo's YQL API to extract HTML from other websites, but yahoo stopped the API and Yahoo's YQL API for extracting HTML will not work anymore.

{
 "query": {
  "count": 0,
  "created": "2017-06-26T12:57:49Z",
  "lang": "en-US",
  "meta": {
   "message": "html table is no longer supported. See https://policies.yahoo.com/us/en/yahoo/terms/product-atos/yql/index.htm for YQL Terms of Use"
  },
  "results": null
 }
}

It can be read here.

This is how I did it so far:

$(function () {
    var fileFieldId;
    var fileFieldClass;
    var query;
    var apiUrl;
    $(".data-from-url").keyup(function () {
        fileFieldId = $(this).attr('id');
        fileFieldClass = $(this).attr('class');
        fileFieldVal = $(this).val();
        query = 'select * from html where url="' + $(this).val() + '" and xpath="*"';
        apiUrl = 'https://query.yahooapis.com/v1/public/yql?q=' + encodeURIComponent(query);

        $.get(apiUrl, function(data) {
          var html = $(data).find('html');
          $("input.post[data-title='" + fileFieldId + "']" ).val(html.find("meta[property='og:title']").attr('content') || 'no title found');
          $("textarea.post-description[data-description='" + fileFieldId + "']" ).val(html.find("meta[property='og:description']").attr('content') || 'no title found');
          $("input.post-remote-image[data-img='" + fileFieldId + "']" ).val(html.find("meta[property='og:image']").attr('content') || '');

    });

});

Here is a jsfiddle for call I am doing

  $(function () {
      var query;
      var apiUrl;
      $("button.click").click(function () {
          //query = 'select * from htmlstring where url="' + $(this).val() + '" and xpath="//a"&format=json&env=store://datatables.org/alltableswithkeys&callback=';
          apiUrl = "https://query.yahooapis.com/v1/public/yql?q=select * from htmlstring where url='http://stackoverflow.com/'&format=json&diagnostics=true&env=store://datatables.org/alltableswithkeys&callback=";
          $('p.extract').toggle();
          $.get(apiUrl, function(data) {
           $('p.extract').addClass('none');
            var html = $(data).find('html');
            $("input.title" ).val(html.find("meta[property='og:title']").attr('content') || 'no title found');
             $("textarea.description").val(html.find("meta[property='og:description']").attr('content') || 'no title found');
            $("input.image").val(html.find("meta[property='og:image']").attr('content') || '');

      });

  });
    });

input {
    width: 100%;
    margin-bottom: 20px;
    padding: 10px;
}

.none{display:none;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="click">Click Me</button>

<input type="text" class="title">

<textarea name="" id="" cols="30" rows="5" class="description"></textarea>

Is there other alternative for extracting HTML meta from other sites head?

You might be able to read the meta tags using queryselector? I use fetch to grab google docs which helpfully has all the document properties in the html meta tags. I then put the html into a temporary object which I can hit with queryselector as I see fit. Something like:

var url = "https://docs.google.com/presentation/d/1blSsU5LHnrjSjb7voHXkRA_NlWo3yNjLiyttmoWfslM/edit#slide=id.gcb9a0b074_1_0"
var id = url.split("://")[1].split("/")[3];
var source = "https://docs.google.com/presentation/d/" + id + "/edit?usp=sharing";
fetch(source).then(function(response) {
        return response.text();
    }).then(function(html) {
        var doc = document.implementation.createHTMLDocument("foo");
        doc.documentElement.innerHTML = html;
        return doc.querySelector("meta[property='og:description']").getAttribute("content");
    }).then(function(title) {
       console.log("document title", title);
    });
