Google app engine endpoints api python

I am facing a problem in endpoint. I am using google app engine on local machine. I am trying to make a endpoint api. The api is created successfully but when i open explorer and select my api give some parameters to it. It does not return response. In response it said 404 not found

Here is the code:

api.py

import endpoints
import protorpc

from ModelClasses import test


import main

@endpoints.api(name="test",version="v1",description="testingapi",hostname="login-test-1208.appspot.com")
class testapi(protorpc.remote.Service):



    @test.method(name="userinsert",path="userinsert",http_method="POST")
    def userinsert(self,request):

        qr = test()
        qr.user = request.user
        qr.passw = request.passw

        qr.put()
        return qr


app = endpoints.api_server([testapi],restricted=False)

ModelClasses.py

from endpoints_proto_datastore.ndb import EndpointsModel
from google.appengine.ext import ndb



class test(EndpointsModel):

    user = ndb.StringProperty(required=True)
    passw = ndb.StringProperty(required=True)
