title: Getting Json data from API and Displaying only part of the json in Unity C#
body: <p>I'm having trouble getting just the price value from <a href="https://api.coindesk.com/v1/bpi/currentprice/XBT.json" rel="nofollow noreferrer">this API</a>. I don't need all the JSON that's coming from the web URL, I only need the <code>"rate":"3,394.2033"</code> part. </p>
  
  <p>API Data: </p>
  
  <pre><code>{
    "time": {
      "updated": "Feb 6, 2019 22:02:00 UTC",

    }
  }

  <p>My Code: </p>
  
  <pre><code>using System;
  using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  using UnityEngine.UI;
  
  public class API : MonoBehaviour
  {
      private string www = 
      "https://api.coindesk.com/v1/bpi/currentprice/XBT.json";
      public Text responseText;
  
      public void Request()
      {
          WWW request = new WWW(www);
          StartCoroutine(OnResponse(request));
      }
      private IEnumerator OnResponse(WWW req)
      {
          yield return req;
  
          responseText.text = req.text;
      }
  }
  </code></pre>
  
  <p>This script allows me to pull all the JSON data but I only need the <code>"rate":"3,394.2033"</code>. More specifically, just the value <code>3,394.2033</code>.</p>
