A unified framework to connect to different Crypto Exchange websites.

I am NOT associated, I repeat NOT associated to any Exchange website. Please use at your OWN risk.

Want to help me? You can tip me :)

• Bittrex (https://www.bittrex.com/) Official API documentation: https://bittrex.com/home/api

• Cryptopia (https://www.cryptopia.co.nz/) Official Public API documentation: https://www.cryptopia.co.nz/Forum/Thread/255

Official Private API documentation: https://www.cryptopia.co.nz/Forum/Thread/256

• Coinexchange (https://www.coinexchange.io/) NOTE, Coinexchange only has public api.

All the exchanges uses API keys. Each API key consists of a public and a private key. NEVER and I repeat NEVER expose your api keys to anybody! If somebody has your API keys, this person can sell/buy/withdraw from you account!

If you do suspect somebody has your api keys DELETE your api keys at once!!!

Also, a lot of exchanges have the option to make you api keys more secure with the option to sell/buy/withdra option. So if you can have an api key with only read rights and no sell/buy/withdraw right. But that depends on the exchange.

One more time: NEVER EXPOSE YOUR API KEYS TO ANYBODY!!!!

fetch the project via git:

$ git clone https://github.com/fransyozef/cryptofyer

Each exchange sits in its own folder and there you'll find 'config.example.inc.php'.

• Rename 'config.example.inc.php' to config.inc.php.
• Edit your key and secret in config.inc.php.

The exchange classes have some required functions to implement:

• buy() -> place a buy order
• sell() -> place a sell order
• getOrders() -> get open orders
• getOrder() -> get order
• cancel() -> cancel order
• getTicker() -> get currency information
• getCurrencyUrl() -> get the exchange currency detail url
• getMarketHistory() -> get market history
• getBalance() -> get balance

When I started with this unified api platform, I used Bittrex's API as a model. Bittrex's string literal for the marketpair is [market]-[currency] for example : BTC-ETH.

After Bittrex I implemented Cryptopia's API. Cryptopia's string literal for the marketpair is [currency]-[market] for example : ETH-BTC.

In order to normalize the market literal string you can use the getMarketPair() function.

$_market = "USDT";
$_currency = "BTC";

$exchange  = new BittrexApi($apiKey , $apiSecret );
$market   = $exchange->getMarketPair($_market , $_currency);

Here you see $market has the value 'USDT-BTC'.

$_market = "USDT";
$_currency = "BTC";

$exchange  = new CryptopiaApi($apiKey , $apiSecret );
$market   = $exchange->getMarketPair($_market , $_currency);

Here you see $market has the value 'BTC-USDT'.

In the future, each exchange api class has a getMarketPair() function to retrieve the right pair notation.

Some functions requires the market string literal as argument. For example Bittrex's ticker:

$result = $exchange->getTicker(array("market" => "BTC-ETH"));
debug($result);

or Cryptopia's ticker :

$result = $exchange->getTicker(array("market" => "ETH-BTC"));
debug($result);

As you can see, the market value is different. To normalize, I added 2 special arguments :

• _market
• _currency

for example :

$result = $exchange->getTicker(array("_market" => "BTC" , "_currency" => "ETH"));
debug($result);

The function will resolve the market pair with the getMarketPair() function.

In the tests folder you will find some examples where you can see the normalization of functions.

• More Exchanges Api
• Better unified functions/notations
• Cleanup code
• Better documentation
