Need some clarity on Rest API

Hi,
I am making a simple TODO app. where user can enter there email and a list of items to do.
I am planning to expose the following API (using spring mvc for this) :

 @RequestMapping(value = "/todo", method = RequestMethod.POST)
    @ResponseBody
    public APIPOSTResponse createTodo(@RequestBody User user) {
        if (user != null) {
            return userService.addUser(user);
        }
        return new APIPOSTResponse(false, "Couldn't add user at this time");
    }

    @RequestMapping(value = "/todo/{id}", method = RequestMethod.GET)
    @ResponseBody
    public ModelAndView viewTodo(@PathVariable int id, HttpServletRequest request) {
        User user = userService.getUser(id);
        ModelAndView mav = new ModelAndView("view");
        mav.addObject("name", user.getUserName());
        mav.addObject("email", user.getEmail());
        mav.addObject("todo", user.getTodo());
        return mav;
    }
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public ModelAndView emptyGet() {
        return new ModelAndView("new");

    }

Select allOpen in new window

Currently the above code only does todo creation and viewing
so initially i land on localhost:8080 where i enter my todo items.
on clicking on create the data goes into database. and from ajax there is a call to localhost/todo/ POST request to save the data into database.
there is a unique id assigned to the user. and then the for viewing there is a GET request to localhost/todo/1 (where 1 is the id here i am assuming)

Other things i am planning to add is the following requests  :
1) localhost/todo/1/edit  GET request to provide user with a page to edit the TODO list items
2) localhost/todo/1  PUT request to update the todo items

So in all there are following api calls  :
1) GET localhost:8080/
2) POST localhost:8080/todo
3) GET localhost:8080/todo/1
4) GET localhost:8080/todo/1/edit
5) PUT localhost:8080/todo/1

As per my understanding this is in compiliance with REST API and thats what REST API means.
Please correct my understanding

Thanks
