You ideally should have these 4 items as variables, as someone else may have good reason to have it set differently on their system for whatever reason. It would mean that you could give a nice error message rather than a 404 if the api version is upgraded on the server.

The capabilities call has been there from before I started working on the code if I remember right. I made the change such that it would no longer require the api version, and increased it's importance.

I'd also add an option to revert to the default button. It is recommended to use http://api.openstreetmap.org/api so that in the future the appropriate load balancing can be done at the dns/network level.

It's up to you whether you require or make optional the /api.
