Google Apps Script messing up JSON values - json

Question

I´m using a Google Apps Script, trying to import Bitcoin-exchange rate information to a Google Spreadsheet. I use this code:
var url = "https://btc-e.com/api/2/btc_usd/ticker";
var response = UrlFetchApp.fetch(url);
var json = response.getContentText();
var lcharts_data = JSON.parse(json)
function bitcoin(){
var b = lcharts_data["ticker"]["avg"];
return b;
}
The JSON-file looks like this:
{"ticker":
{"high":947.99902,
"low":817.64001,
"avg":882.819515,
"vol":24625847.06001,
"vol_cur":28189.09956,
"last":930,
"buy":930,
"sell":929.998,
"updated":1385575341,
"server_time":1385575342}
}
}
Yet b returns as 22.49. What am i doing wrong?

Answer 1

I use the similar method for receiving the data but I parse it slightly different. For example:
var url = "https://btc-e.com/api/2/btc_usd/ticker";
var response = UrlFetchApp.fetch(url);
var json = response.toString();
var lcharts_data = JSON.parse(json);
Notice the toString() method and the native Utilities.jsonParse() method. I tried JSON.parse() but that didn't work for me.
Also are using an API key to access the data? Have tried above but it's timing out.

As at when I tested your url, the JSON response returned was:
{
"ticker":{
"high":421.70001,
"low":418,
"avg":419.850005,
"vol":2361935.91952,
"vol_cur":5620.41595,
"last":420.168,
"buy":420.168,
"sell":419.853,
"updated":1460626271,
"server_time":1460626273
}
}
Here's the code that returns the value for 'avg':
var url = "https://btc-e.com/api/2/btc_usd/ticker";
var response = UrlFetchApp.fetch(url);
var json = response.getContentText();
var lcharts_data = JSON.parse(json);
function bitcoin(){
var b = lcharts_data.ticker.avg;
return b;
}
