Welcome to Echobox.

Echobox is a Sinatra web app that accepts messages at any route and echos back all parameters in a json response as well as success => true by default (override as a query string parameter). Echobox is useful for testing applications that consume and send JSON.

For example, http://echobox.me/?foo=bar will return JSON that looks something like this:

{
    "splat": [
        ""
    ],
    "foo": "bar",
    "success": true,
    "source": "http://echobox.me/?foo=bar" 
}    

You can specify a callback for JSONP like this http://echobox.me/?foo=bar&callback=callback:

callback({"splat":[""],"callback":"callback","foo":"bar","success":true,"source":"http://echobox.me/?foo=bar&callback=callback"})
