This is a little off topic and maybe controversial because it is against the spirit of open source but in all earnestness if you make a software that you want to make available to all open source projects but then you want to charge a recurring monthly fees if the software is being used to make money - is there a standard license for that?

I've seen sites do this like readme.io but can you do that for a software library?

It's called a dual license. And yes, you can do it for anything. Copyright is automatic, and it grants you control over the right to copy your creation. You just need to make sure you're the one that created it.

Found this to be a good overview:

Have you taken a look at what http://www.highcharts.com does? I haven't read their license but the model seems similar to what your looking for.
