How to use the enterprise Geodatabase featureclass metadata in ArcGIS Server Javascript API application?

[Muqit_Zoarder]

Dear all, I have my enterprise geodatabase in sql server DB. I have created the mapservice with 36 layers in one service. Now i want to use the background metadata in my web application. How can i use each layer metadata in my application beside each layer? See the example images, in first image we can see beside each layer there is a Info link to view the metadata and in the second image is showing the metadata page by clicking the Info link. Please suggest me the right way. thanks.

 Dear Muqit Zoarder, I am also looking for same approach. If possible can you share any references regarding approach to do this, if you got solution? It will be grateful if you share workaround sample.

Muqit & SriHarsha,

Metadata of a service or a particular layer can be retrieved by the typical rest service calls to your service.

For example, the below is a call to service that returns metadata in json format for the service itself.
Service URL: https://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Network/USA/NAServer/Service%20Area 

Metadata call: https://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Network/USA/NAServer/Service%20Area?f=js... 

Here it returns metadata for a particular layer.
