Hello
In above all solutions USD to CNY converter not working

Can you please help me

Thanks!!

Yes! Сan you give another solution?

can anyone pls help me with any free currency converter api?

Any solutions!!

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");

Here we are again :(
