This just delivers a blank page.

The API returns JSON output, so naturally you'd need to decode the output in order to access the nested object property:

Code:

$obj = json_decode($result);

/*
echo"";
print_r($obj);
echo"
";
*/

echo $obj->result->Bid;

Great thank you that worked, if I could though one more question :

What is the difference between this out put https://yobit.net/api/3/ticker/swing_btc and the trex one ?

Your answer worked perfectly for trex but not for yobit :

Code:

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'https://yobit.net/api/3/ticker/swing_btc');
$result = curl_exec($ch);
curl_close($ch);

$obj = json_decode($result);

/*
echo"";
print_r($obj);
echo"
";
*/

echo $obj->result->high;
?>

And

Code:

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'https://yobit.net/api/3/ticker/swing_btc');
$result = curl_exec($ch);
curl_close($ch);

echo $obj[0]->high;
?>

I understand the Trex being json format but the Yobit one isnt ( is it ? ) so in my mind your original answer from coinmarketcap should have worked

Thanks again

This is confusing

So using the very helpful reply above I have tried using it to retrieve a coin price from Trex

API link
https://bittrex.com/api/v1.1/public/getticker/?market=btc-swing

Gives me a response of

Code:

{"success":true,"message":"","result":{"Bid":0.00004331,"Ask":0.00004963,"Last":0.00004331}}

So based on my now working code for the MarketCap ( Thanks sotisoti ) my logic would tell me i can use the same code for Trex .... But no that would be too simple, so what have i done wrong here:

Code:

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'https://bittrex.com/api/v1.1/public/getticker/?market=btc-swing');
$result = curl_exec($ch);
curl_close($ch);

echo $obj[0]->Bid;
?>

This just delivers a blank page.

Thanks again for any help, I will get my head around this API stuff lol

Try
echo $obj[0]->market_cap_usd;

Or

Code:

$array = json_decode($result, true);
echo $array[0]['market_cap_usd'];

if you want array

That worked perfect - Thank You

Can someone tell me how I can display just the market cap on a webpage using this API

https://api.coinmarketcap.com/v1/ticker/swing

So you will see that returns :

Code:

[
    {
        "id": "swing", 
        "name": "Swing", 
        "symbol": "SWING", 
        "rank": "236", 
        "price_usd": "0.0453786", 
        "price_btc": "0.00004855", 
        "24h_volume_usd": "225.625", 
        "market_cap_usd": "87028.0", 
        "available_supply": "1917815.0", 
        "total_supply": "1917815.0", 
        "percent_change_1h": "5.99", 
        "percent_change_24h": "-0.35", 
        "percent_change_7d": "-9.67", 
        "last_updated": "1485862761"
    }
]

But the only bit I want to display is "market_cap_usd"

Ive tried all sorts such as https://api.coinmarketcap.com/v1/ticker/swing?market_cap_usd

and things like this:

Code:

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'https://api.coinmarketcap.com/v1/ticker/swing/');
$result = curl_exec($ch);
curl_close($ch);

$obj = json_decode($result);
echo $result->market_cap_usd;


?>

But cant make it work

Many Thanks for answers
