How to identify if API's are enabled ?

Question

Our JIRA is hosted at http://backlog.acquia.com/. I am not the Admin, instead just a user.

How do I identify if API's are installed / enabled.

I am trying to hit the REST URL's like "rest/api/2/issue/KEY-ID" and get 401. But this response can be because, I am using UN / PW, where as we use Google account to Login.

How do I firstly make sure, that API is enabled.

Thanks

It's often in the footer of the pages, but if not, it is available in help -> about.

As I said already, the API is always on in later versions.

Ok, in that case, how do I identify the version of JIRA ?

If this is 6.4+, am I correct to assume that the rest services are always ON and I will be able to access them, via the API's ?
