This works for me

    import urllib2
    import json
    curr_from = "JPY"
    curr_to = "INR"
    curr_input = 1
    curr_pair = curr_from + "_" + curr_to
    api_url = "https://free.currencyconverterapi.com/api/v5/convert?q={0}&compact=ultra".format(curr_pair)
    jsonurl = urllib2.urlopen(api_url)
    rate_json = json.loads(jsonurl.read())
    rate = curr_input * float(rate_json[curr_pair])
    print rate

As google shut down converter link you just need to replace url given below

Just replace:
https://www.google.com/finance/converter?a=
https://finance.google.com/finance/converter?a=
https://finance.google.com/bctzjpnsun/converter?a=
http://free.currencyconverterapi.com/api/v3/convert?q=

with this URL:
https://www.xe.com/currencyconverter/convert/?Amount=

Thanks for referencing free.currencyconverterapi.com , please use the "v5" onwards API. And just to give a quick update, refresh values are now updated every 60 minutes.

Friends don't worry i made the converter working again use the following code
`<?php
function convertCurrency($amount, $from, $to){
$data = file_get_contents("https://www.xe.com/currencyconverter/convert/?Amount=$amount&From=$from&To=$to");
//var_dump($data);
$doc = new DOMDocument;
$doc->loadHTML($data);

$xpath = new DOMXPath($doc);
$node  = $xpath->query("//span[@class='uccResultAmount']")->item(0);
echo trim($node->nodeValue); //=> "$249.95"

}
echo convertCurrency("1", "INR", "USD");`

This is the code my application uses for the google currency api; what would be the code I should use for the free currency converter api? Nothing I've tried works.

function convert($from,$to,$amount) {

    $url = "https://finance.google.com/bctzjpnsun/converter?a=1&from=" . $from . "&to=" . $to;
    $page = file_get_contents($url);
    preg_match_all("/bld>(.*) .*/", $page, $matches);

    $value = $matches[1][0];

    $response = (float) $value * $amount;

    return $response;

}

Fixed:

function convert($from,$to,$amount){
    $url = "https://www.google.com/search?q=".$from.$to;
    $request = curl_init();
    $timeOut = 0;
    curl_setopt ($request, CURLOPT_URL, $url);
    curl_setopt ($request, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt ($request, CURLOPT_USERAGENT,"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36");
    curl_setopt ($request, CURLOPT_CONNECTTIMEOUT, $timeOut);
    $response = curl_exec($request);
    curl_close($request);

    preg_match('~<span [^>]* id="knowledge-currency__tgt-amount"[^>]*>(.*?)</span>~si', $response, $finalData);
    return floatval((floatval(preg_replace("/[^-0-9\.]/","", $finalData[1]))/100) * $amount);
}

Thank you, Alisson, this works like a charm. The only thing was I had to delete "/100" in the last line.

Thanks a lot @alissonlinneker.
Though I'd suggest replacing $url with:
$url = "https://www.google.com/search?q=".$from."+to+".$to;
because in some cases like BRL to CAD, Above function was throwing exception.

Need a little help here,
I used above code, tested it on my local environment and it worked smooth as butter, but once I uploaded this to my production environment, it started throwing errors, I debugged and found that Google isn't allowing this code to scrape their data. It gives "302 Moved" Error. Further explanation from Google is: "Our systems have detected unusual traffic from your computer network. Please try your request again later". So, anybody has any tip for that??

It is not the best solution and not very clean, but you can do this:

  1. Convert from your old currency to BTC (Bitcoin)
  2. Convert your Bitcoin to your new currency! ;-)

Example for 100 EUR to USD:

  1. 100 EUR to Bitcoin. Result: 0.01282849
    https://blockchain.info/tobtc?currency=EUR&value=100

  2. Convert 01282849 (without "0.") to USD
    https://blockchain.info/frombtc?value=01282849&currency=USD

Attention: In this solution you can convert max 1 full Bitcoin (~8000 EUR)
PHP Code:

function convert($amount, $from, $to)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://blockchain.info/tobtc?currency=" . $from . "&value=" . $amount);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$conversion = curl_exec($ch);
$conversion = substr($conversion, 2);
curl_setopt($ch, CURLOPT_URL, "https://blockchain.info/frombtc?currency=" . $to . "&value=" . $conversion);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
return $conversion = curl_exec($ch);
}
echo convert(100, "EUR", "USD");
