What API version are you working with?

In 3.19 you can easily get the visible layers through the map objects different layer properties e.g.

map.layerIds or map.graphicsLayerIds

Then you can check if the layer is visible, get the URL for the layer and get the layer properties as JSON through a standard request (https://[server]/arcgis/rest/services/[service]/MapServer/[layerID]/?f=pjson)

Prasad,

You could use the IdentifyTask for this if you do not want to send a query to each individual layer.

Take a look at this discussion, which returns the map service information for layers in different services.

Get an IdentifyParameter for an IdentifyTask result
