Where is a good start to make price scripts from exchanges for my website?

do you want to add like a price indicator to your website or option to buy and sell through exchanger's API

i am not an expert but for the first you can add a price widget to your site like this:

Code:

<div id="coindesk-widget"></div>
<script type="text/javascript" src="//widget.coindesk.com/bpiticker/coindesk-widget.min.js?509e9d"></script>

I want to understand API exchange

API exchange is basically sending an http request to the exchanger with what you want to do and signing it with your API secret key for security.
and example:
{APIRequestURI}/createorder&MarketName=BTC_USD&Amount=1&type=sell&price=420

then sign this with API secret and send it via POST method and receive the JSON response.

I can probably write a couple price widgets for you, so you can use them directly onto your site, and learn from the samples?
PM me for a quote if you're interested!

Thanks for the help from @mocacinno

But I have a question from bittrex api, I have this code

Code:

<?php
$url = 'https://bittrex.com/api/v1.1/public/getmarketsummary?market=btc-nlg';
$response = file_get_contents($url);
$obj = json_decode($response,true);
echo '&#579; '. $obj['result'][0]['Ask'] . '
';
?>

My question, the code show
Bittrex Ƀ 4.74E-6 and I want something like this Bittrex Ƀ 0.00000474

[pooya87]

~~
Bittrex Ƀ 4.74E-6 and I want something like this Bittrex Ƀ 0.00000474

they are both the same 4.74E-6 is the scientific method of showing the number.
by the time of displaying the result in your output you have to just change the "format".

most of the time i do this in c#

Code:

txtOutput.Text = string.Format("{0:0.00000000}",4.74E-6);

i don't know about PHP, so google can help you better:

As pooya87 said, sprintf would be the best way to do this.
I actually didn't think of this, and advised Bram_vnl to explode the string on "E-", and divide the first ellement of the return array by 10 to the power of [second ellement of the returnarray], but sprintf would be a much better idear

I have change

Code:

$obj = json_decode($response, true);
echo 'Ƀ '. $obj['result'][0]['Last'] . '<br>';

to

Code:

$obj = json_decode($response,true);
echo number_format($obj['result'][0]['Last'], 8);

That works

The last thing I need the php script's for yobit alcurex safecex

[pooya87]

https://yobit.net/api/3/ticker/nlg_btc
since this doesn't have the json_decode($response,true) part you can check for response success some other way (optional)
change the obj to this:

Code:

$obj['nlg_btc']['Last']

the difference here is that the response is not an array. you just have to give the keys to json to reach what you want.

i haven't heard about the other two exchangers

edit:
https://alcurex.org/api/market.php?pair=NLG_btc&last=last

Code:

$obj['nlg_btc']['price']

https://safecex.com/api/getmarket?market=NLG/BTC

Code:

$obj['last']

you might wanna check with mocacinno that knows PHP

Have a look at this newly created exchange's API https://gatecoin.com/api very well structured and easy to understand.Not only for trades but they provide customer ticker's like Market analysis and Depth.Request header's are easier to create as well :

Code:

              jqXHR.setRequestHeader("API_PUBLIC_KEY", publicKey);
                            jqXHR.setRequestHeader("API_REQUEST_SIGNATURE", hashInBase64);
                            jqXHR.setRequestHeader("API_REQUEST_DATE", now);
                        

Not sure what exactly you're looking for but this one should serve all the custom needs.

@mocacinno I have send you a pm

I've seen it, i'm on the road ATM, so it's kinda hard to test out code. I'll see if i can give you a solution this weekend
