I have get some information about ASP Web API.
It is look like good stuff for web services but how to create something like WSDL for my API like WCF service does ?

There is no SOAP or WSDL support in WebApi.
If you like WebApi you will love ServiceStack who has support for both REST and SOAP.
You can genereate WSDL with service stack even for REST Services.
