Getting errror on WebAPI

I'm getting following response while calling OData api.


Response failed (?):
cache-control: no-cache
content-type: application/json; charset=utf-8
expires: -1
pragma: no-cache

{
"Message": "No HTTP resource was found that matches the request URI 'http://localhost/oda...nt=allpages'.",
"MessageDetail": "No type was found that matches the controller named 'Customers'."
}

what should I do to rectify the problem.

Or how to configure the webapi.

Using version : 4.0.1

Hi muthusamy, could you fix that problem? Greetings Stefan
