Question

is there a way to query the play store for the version of an app without the need for user-credentials. I am aware of this unofficial API:

It's unofficial but easy to use (free for non commercial use). you can get data about apps, search the play store and get top charts data. from their documentation section:

Node.js:

var request     = require('request');
var apiKey      = 'wij5czxu3mxkzkt9'; // your API key
var packageName = 'com.whatsapp';     // package Name, e.g. com.whatsapp for WhatsApp

var url = 'http://api.playstoreapi.com/v1.1/apps/' + packageName + '?key=' + apiKey;

request({
    url: url,
    json: true
    }, function (error, response, body) {
    if (!error && response.statusCode === 200) {
        console.log(body) // Print the json response
    }
});

HTML/JS:

Python:

import urllib2
import json

packageName = 'com.whatsapp'      # package com.whatsapp for WhatsApp
apiKey      = 'wij5czxu3mxkzkt9'  # your API key

url = 'http://api.playstoreapi.com/v1.1/apps/{0}?key={1}'

response = urllib2.urlopen(url.format(packageName, apiKey))

data = json.load(response)   
print data

C# .NET:

string apiKey = "wij5czxu3mxkzkt9"; // your API key
string app    = "com.whatsapp";     // package com.whatsapp for WhatsApp

string url = "http://api.playstoreapi.com/v1.1/apps/{0}?key={1}";

using (var webClient = new System.Net.WebClient()) {
    string jsonString = webClient.DownloadString(string.Format(url, app, apiKey));
}
