You can get this data easily by scraping or by using the websocket interface that Stack Exchange helpfully leaves available.
If you are making an application or webpage, just fetch stackoverflow.com/10m via your app-language's standard fetch/scrape utilities. EG: cURL if you are using PHP, etc.
For client side applications, make a Greasemonkey/Tampermonkey/user script and use GM_xmlhttpRequest(). It doesn't have the CORS restrictions.
For super-realtime, JS driven pages, the websocket is open cross-domain (at least until too many people abuse it).
See an example using the websocket at jsBin.
Or run this code from your browser's console:
var ws = new WebSocket("ws://qa.sockets.stackexchange.com/");
ws.onmessage = function (messObj) {
var payload = JSON.parse (messObj.data);
var statName;
switch (payload.action) {
case "1-qcnt-feed":
statName = 'Questions';
break;
case "1-acnt-feed":
statName = 'Answers';
break;
case "1-evc-feed":
statName = 'Edits, Votes and Comments';
break;
default:
statName = 'Error! action == "' + payload.action + '".';
break;
}
console.log (statName + ': ' + payload.data);
};
ws.onopen = function () {
ws.send ("1-evc-feed");
ws.send ("1-acnt-feed");
ws.send ("1-qcnt-feed");
};
window.ws = ws; //debug: Allows you to enter ws.close() from console.
