Looking to display Bitcoin price plus extra % that i will set

[pamamolf]

Hi

I am looking for someone that can write a few lines of code (maybe use an API) so i can display the current bitcoin price plus an extra % that i will be able to set on a site.

Maybe use a div so it will be easy to use the code in any place on my page.

Thank you

Here's a simple one I created in PHPfiddle:  http://phpfiddle.org/lite/code/9mbw-iu5v

http://btcthreads.com/how-to-get-the-current-bitcoin-price/

Code:

$url = "https://coinbase.com/api/v1/prices/spot_rate";
$json = json_decode(file_get_contents($url), true);
$price = $json["amount"];
$addP = $price * 1.05; //add 5% to the current exchange rate
echo $addP;

Nice little script, good work.

Great THANKS

But can you add a few lines of ajax so it can auto refresh?

[batesresearch]

You can add

header("refresh: 240;"); on the next line after the <?php

^ That's a 240 refresh second, just watch the amount of times your pulling from the API don't exceed the limit

popen("pythonfile.py"); //apparently this works!

pythonfile.py

Code:

 
import time
time.sleep(5)

SORRY! for using a previous person's content, i think this should work! If the content owner is unhappy with this, I will remove it (please pm if unhappy)!
I would suggest that you use the preev.com api (it refreshes faster!)

or this!

preev.com is cool but no idea how to use the api of them

Not a good idea, you'll get banned for hitting the API too many times, but here you go.


HTML:
index.html

Code:

<script src="ajax.js"></script>
<script type="text/javascript">
refreshdiv();
</script>
<div id="pricediv"></div>

AJAX:
ajax.js

Code:

var seconds = 5;
var divid = "pricediv";
var url = "price.php";

function refreshdiv(){
	var xmlHttp;
	try{
	xmlHttp=new XMLHttpRequest(); // Firefox, Opera 8.0+, Safari
	}
		catch (e){
		try{
		xmlHttp=new ActiveXObject("Msxml2.XMLHTTP"); // Internet Explorer
		}
		catch (e){
			try{
			xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
			}
			catch (e){
			alert("Your browser does not support AJAX.");
			return false;
			}
		}
	}

fetch_unix_timestamp = function()
{
return parseInt(new Date().getTime().toString().substring(0, 10))
}

	var timestamp = fetch_unix_timestamp();
	var nocacheurl = url+"?t="+timestamp;

	xmlHttp.onreadystatechange=function(){
		if(xmlHttp.readyState==4){
		document.getElementById(divid).innerHTML=xmlHttp.responseText;
		setTimeout('refreshdiv()',seconds*1000);
		}
	}
	xmlHttp.open("GET",nocacheurl,true);
	xmlHttp.send(null);
}

var seconds;
window.onload = function startrefresh(){
setTimeout('refreshdiv()',seconds*1000);
}

PHP
price.php

Code:

$url = "https://coinbase.com/api/v1/prices/spot_rate";
$json = json_decode(file_get_contents($url), true);
$price = $json["amount"];
$addP = $price * 1.05; //add 5% to the current exchange rate
echo $addP;

Great thanks !!!

But:

Is there any other way to make it work like preev (auto refresh)  ?

Yes, the way I do it is to set up a database to store the price/market value. Then set a cron job to run every N minutes to update the database with the updated rate.  This way you could have a million visitors and still never exceed the API limits, because you are just querying your own DB instead of hitting them with an API call for every visitor.
