About Exchanges API

[BT TESTING]

Hi!

Anyone know any API that offers all pairs from all exchanges from Bitcoin and altcoins?

Thanks in advance !

You have to use api from individual trading platform and i don't think there is any api which support multiple exchange platforms other than few bots so hard to trust them.

You can check individual exchange api of poloniex and bittrex which support both bitcoin and altcoin trading

https://bittrex.com/Home/Api

I'm not sure If I got your request right but If you are looking to gather information's about different altcoins and Bitcoin  like Marketcap , supply , trading moves etc... then coinmarketcap API should be a great choice.

http://cryptocoincharts.info has an easy to use API that pulls info from 50+ exchanges and displays trading data for hundreds of coins.

Code:

<?php
$pair="btc_usd";
$curl=curl_init();
curl_setopt($curl, CURLOPT_URL, "http://api.cryptocoincharts.info/tradingPair/".$pair);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$rawData=curl_exec($curl);
curl_close($curl);
$data=json_decode($rawData);
$btcprice=$data->price;
echo $btcprice;
?>
