What's the correct way to expose a requireJS module to the global namespace?

I want to expose a Javascript API as a standalone library without polluting their global namespace. I've created the wrapper so I don't pollute their own requireJS according to http://requirejs.org/docs/faq-advanced.html. I've simplified what I have so far as below, but I'm not sure if this is the correct way or if I should be doing it some other way.

var MyApi = MyApi || {};
var MyApiRequireJS = (function() {
  // require.js pasted here
  return {requirejs: requirejs, require: require, define: define};
})();

(function(require, define, requirejs) {
  require.config({
    baseUrl: 'js/scripts',
    waitSeconds: 30,
  });  

  define( 'myapi', ['jquery', 'underscore'],
    function($, _) {
      $.noConflict(true);
      _.noConflict();
      function api(method, args, callback) {
        // do stuff here
      }
      return {api: api};
    }
  );

  require( ['myapi'], function( myapi ) {
    MyApi = myapi;
  });
}(MyApiRequireJS.require, MyApiRequireJS.define, MyApiRequireJS.requirejs));

Sites using this library would include a script tag referencing the above code and then call the api using

MyApi.api('some_remote_method', {foo: 'bar'}, function(result) {
  // handle the result
});
