Trello responds 'invalid key'

问题

I am trying to get JSON data for a Trello board using the following URL, using Node.js's https module:

https://trello.com/b/nC8QJJoZ.json

Here's my code:

var https = require('https');

https.get('https://trello.com/b/nC8QJJoZ.json', function (res) {
    console.log('statusCode:', res.statusCode);
    console.log('headers:');
    console.log(res.headers);
    res.setEncoding('utf8');

    res.on('data', function (chunk) {
        console.log(chunk);
    });
}).on('error', function (e) {
    console.log('ERROR: ' + e);
});

Although the URL works perfectly in browser, It returns a body containing the string "invalid key", with a 401 status. Following is the output:

statusCode: 401
headers:

invalid key

What am I doing wrong?

Well, it turns out that we need to provide a Trello API application key (generated from here) with our request.

var https = require('https');
var KEY = '<replace this with your app key>';

https.get('https://trello.com/b/nC8QJJoZ.json?key=' + KEY, function (res) {
    ...
});

This seems to me a weird requirement because we are not using Trello's API endpoint. (Even if I solved the problem, I would still like to know why a browser can access the resource, but a server side script cannot.)
