[CLOSED] BOUNTY: 10 BTC for a simple script

[Trader Steve]

Greetings Coders,

I am looking for a simple script that will do the following:

Display the price of 1 gram of silver in U.S. dollars

Additional info:

The spot price of silver is usually quoted in troy ounces on sites like www.kitco.com. Here is the conversion formula:

1 troy ounce = 31.1034768 grams

Please PM me if you are interested.

Thanks,
Trader Steve

php?

Do you have your own feed source for the data?

more info please:

what scripting language?
which site to get the info from?

Code:

<?php
$decimals = 2;

$ticker = json_decode(file_get_contents('http://drayah.no.de/metals/latest'), TRUE);
$silver = $ticker['silver']['quote'];

echo round($silver/31.1034768, $decimals);
?>

drayah's node.js box parses the prices from kitco.com.

Update: Here's a version that fallbacks to http://services.packetizer.com/spotprices/ if drayah's service is down (I'm keeping the old one for posterity):

Code:

<?php
$decimals = 2;

$drayah = json_decode(file_get_contents('http://drayah.no.de/metals/latest'), TRUE);
if ($drayah['silver']['quote'] > 0) {
	$silver = $drayah['silver']['quote'];
} else {
	$packetizer = new SimpleXMLElement(file_get_contents('http://services.packetizer.com/spotprices/?f=xml'));
	$silver = $packetizer->silver;
}

echo round($silver/31.1034768, $decimals);
?>

Update 2: Made another change should drayah's service be up but kitco down.
