query trello api to view list with card and query label

I'm using node-trello npm plugin to query my board. I have multiple lists with lots of cards in it respectively. I want to query on the lists and then query the labels. For example, if my list name is working and in that list I'm using different labels such as one, two then I want to query list working with label one. I tried to look at the API but could not figure out.

Here is my progress:

var Trello = require("node-trello");
var t = new Trello("<key>", "<token>");

t.get("/1/boards/<board-id>/lists", function(err, data) {
  if (err) throw err;
  console.log(data);
});
