So I'm trying to have the result that's received from sending a HTTP GET request to an HTTP API set as the result of a div. How can I go about loading the result from the API?

I would do an XMLHttpRequest. You could also use cURL in PHP, but if your wanting to achieve this in JavaScript, use this script.
Now all you need in the html is a way of calling the method (say on the click of a button or onload), and the div id of whatever you call in the code above.
function someFunctionToLoadStuff()
{
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("content").innerHTML=xmlhttp.responseText; //change content to anything you want.
}
}
var url = "file";
xmlhttp.open("POST",url,true);
xmlhttp.send();
}

Hey, I can't seem to get that to work with the following code.
var xmlhttp;
function someFunctionToLoadStuff()
{
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("result").innerHTML=xmlhttp.responseText; //change content to anything
}
}
function listener()
{
var url = "http://www.somewebsite.com/?tool=skyperesolver&username=live:dean.hemmingfield";
xmlhttp.open("POST",url,true);
xmlhttp.send();
someFunctionToLoadStuff;

My apologies. I thought you were trying to achieve this from a file on your own server.
To grab it from another URL, use cURL in PHP. Here is an example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Grab Test</title>
</head>
<body>
<h2>Grab Stuff</h2>
<?php
if(isset($_POST['submitBtn'])) {
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, 'http://pastebin.com/raw.php?i=fkNDcc7i');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
echo $data;
}
?>
<form action="" method="POST">
<input type="submit" name="submitBtn" value="Click to load" />
</form>
</body>
</html>

Use this
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Grab Test</title>
</head>
<body>
<h2>Grab Stuff</h2>
<?php
if(isset($_POST['submitBtn'])) {
$ch = curl_init();
$timeout = 5;
$query = $_POST['itemToSearch'];
curl_setopt($ch, CURLOPT_URL, 'http://thetechgame.com/raw.php?i={$query}');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
echo $data;
}
?>
<form action="" method="POST">
<input type="text" name="itemToSearch" placeholder="something" />
<input type="submit" name="submitBtn" value="Click to load" />
</form>
</body>
</html>
