How to use PhantomJS to access an API whose response is JSON and not HTML and process the result?

I would like the example to use the Stackoverflow's own Portuguese API, so that the script returns the title and the names of the authors of recently changed issues.

node.js phantomjs

To do this, go to the API interface and find out which URL to use. For this specific case, this is the direct link link

The code below is documented and details how to do this

var page = require('webpage').create();

// Acesse perguncas recentes do pt.stackoverflow
page.open('https://api.stackexchange.com/2.1/questions/no-answers?order=desc&sort=activity&site=pt.stackoverflow', function () {
    var objeto = null, i = 0;

    try {
        // page.plainText retorna o conteúdo da página pura, sem forçar tags HTML em volta e invalidar a resposta como JSON
        objeto = JSON.parse(page.plainText);
    } catch (e) {
        console.log('Erro ao processar resposta em JSON');
    }
    if (objeto && objeto.items && objeto.items.length) {
        for (i = 0; i < objeto.items.length; i +=1) {
            console.log(objeto.items[i].title + ' por ' + objeto.items[i].owner.display_name);
        }
    }
    phantom.exit(); // Finaliza
});

It will print something like
