Restful create URL

I'm creating and api.
I create a scaffold

script/generate scaffold user

I have users controller, but how do I call the create method via a URL

ie...localhost:3000/users/create.xml?params

new doesn't work as it returns the empty user object in XML as it
should,
but when I call create
localhost:3000/users/create.xml?params
I get the below error

"Couldn't find User with ID=create"

I get that is has to do with the routing, but I don't want to call
create with and ID as I don't know what it is going to be.

Any help is apperciated.

Cheers,

Rails defines seven controller methods for RESTful resources by
convention. They are:
