Demo on your main page:

var json = get({
url: 'http://search.twitter.com/search.json',
params: {
q: "@webshell_"
},
format: 'json'
});
dump(json);

result is:

[WebshellHttp] {
errors: [
{
message: "The Twitter REST API v1 is no longer active. Please migrate to API v1.1. https://dev.twitter.com/docs/api/1.1/overview.",
code: 64
}
]
}
