Cyger is a PHP library to get cryptocurrency price from various exchange APIs.
- It is possible to resolve different specifications for each api as soon as possible.
- It can get last price, bid price, ask price and volume.
- Supporting exchanges
$ composer require kuromoka/cyger
- PHP >= 5.5
- Composer
The first example code below shows getting last price of BTC_ETH from Poloniex.
require 'vendor/autoload.php';
use Cyger\Client;
$client = new Client();
$result = $client->setExchange('Poloniex')->setPair('BTC_ETH')->getLastPrice();
echo $result['Poloniex']['BTC_ETH']; // 0.04549105The secound example code below shows getting last price of BTC_ETH from all supporting exchanges. It is possible not to set exchange, but it is necessary to set pairs.
if exchanges don't support pairs, returning NULL.
$client = new Client();
$result = $client->setPair('BTC_ETH')->getLastPrice();
echo $result['Poloniex']['BTC_ETH']; // 0.04549105
echo $result['Bittrex']['BTC_ETH']; // 0.04577
echo $result['Coincheck']['BTC_ETH']; // NULL (Coincheck doesn't support BTC_ETH pair.)Also, you can use various style of exchange name and pair name. You don't have to think each api specifications basically.
The example below shows OK and NG name.
$client->setExchange('poloniex') // OK
$client->setExchange('POLONIEX') // OK
$client->setExchange('POLONIE') // NG
$client->setPair('BTC_ETH'); // OK
$client->setPair('btc-eth'); // OK
$client->setPair('ETH/BTC'); // OK
$client->setPair('BTC:ETH'); // NGKey name of results array is setting from your style.
$client = new Client();
$result = $client->setExchange('POLONIEX')->setPair('ETH/BTC')->getLastPrice();
echo $result['POLONIEX']['ETH/BTC']; // 0.04549105
When you want to get other than last price, please replace getLastPrice() to methods below.
- getBidPrice()
- getAskPrice()
- getVolume()
I am going to add more exchanges in the future.
