What is the consequence of not using a key with google ajax api load

Question

I can call the google api this way with a key :

<script src="http://www.google.com/jsapi?key=ABQIAAAA1XbMiDxx_BTCY2_FkPh06RRaGTYH6UMl8mADNa0YKuWNNa8VNxQEerTAUcfkyrr6OwBovxn7TDAH5Q"&gt;&lt;/script&gt;

But i can also omit to specify a key like this:

<script src="http://www.google.com/jsapi"&gt;&lt;/script&gt;

and my code still work.

What would be the consequence of not using a key ? Could Google block my requests ? Would it be a good idea to use Production code that call Google api for a intranet app ?

Thank you.

Answer 1

It might work for a small number of requests while you're testing out your site, but then stop working once you start getting traffic. Don't risk showing your users a broken page with missing content!

Answer 2

I think, key is used only for some APIs, like Google Maps, and ignored for, for example, jquery hosted on Google CDN.

Answer 3

I think they've recently disabled the no-api working with jQuery does this still work for you?
