XHR is a wrapper around Titanium's HTTPClient. It works perfectly with REST API endpoints and has a built in cache system that you can use for your requests.

In your app.js (or elsewhere), call:

var XHR = require("/lib/xhr");
var xhr = new XHR();
xhr.get("http://freegeoip.net/json/", onSuccessCallback, onErrorCallback, options);

For more information check out the examples.js file. Or browse around the xhr.js file. You can find in there support for GET, POST, PUT and DELETE (called destroy for reserved words problems)
