yahoo_exchange_rates_jsonp.html

Get exchange rate as JSONP via YQL.

YQL Console: http://developer.yahoo.com/yql/console

Query (USD to SEK): select rate,name from csv where url='http://download.finance.yahoo.com/d/quotes?s=USDSEK%3DX&f=l1n' and columns='rate,name'

Example code:

<script type="text/javascript">

  function getRate(from, to) {
    var script = document.createElement('script');
    script.setAttribute('src', "http://query.yahooapis.com/v1/public/yql?q=select%20rate%2Cname%20from%20csv%20where%20url%3D'http%3A%2F%2Fdownload.finance.yahoo.com%2Fd%2Fquotes%3Fs%3D"+from+to+"%253DX%26f%3Dl1n'%20and%20columns%3D'rate%2Cname'&format=json&callback=parseExchangeRate");
    document.body.appendChild(script);
  }

  function parseExchangeRate(data) {
    var name = data.query.results.row.name;
    var rate = parseFloat(data.query.results.row.rate, 10);
    alert("Exchange rate " + name + " is " + rate);
  }
  
  getRate("SEK", "USD");
  getRate("USD", "SEK");
  
</script>

Excelent! works :)

Excelent

Hi! Thanks a lot for the code, works perfectly. One question, how I can store each request as a variable to use it later? For example if i do getRate("SEK", "USD");, how I can store that rate so I can multiply it and get the currency conversion?

This always converts any currency with default amount.

1 is default where in code amount is given 10 to be converted.

I had use this. It works great for me.

Wonderful, thank you for your great work

For example, request: http://query.yahooapis.com/v1/public/yql?q=select%20rate%2Cname%20from%20csv%20where%20url%3D'http%3A%2F%2Fdownload.finance.yahoo.com%2Fd%2Fquotes%3Fs%3DEURUSD%253DX%26f%3Dl1n'%20and%20columns%3D'rate%2Cname'&format=json

Doesn't return results, it's fail.

Re: Is Yahoo! Finance API broken?
Hi All - I'm blocking new replies to this thread since it refers to an older outage.
The new download issue which began 11/01/17 and returning an error 999 for most users is currently being investigated and we hope to have it resolved soon.

More info at Yahoo forum

@kasimvali786 Yahoo has discontinued this API I'm afraid. See the comment before yours.

Hi Henrik,

Yes, I noticed that before comment, do you have any idea is there any link API URL to get the daily exchange rates.

Thanks in advanced.

@kasimvali786
You can use this one

`https://finance.google.com/finance/converter?a=${amout}&from=${from}&to=${to}`

@sheff3rd

This might be too much to ask but can you post an example to convert USD to INR using the above URL ?

Looks like both APIs are not working.
