That's not JSON format data, you can loop thru the object: To get the root key, you could do:

var rootKey;
for(var prop in tst) {
 console.log( prop ); //will give "services"
 rootKey = prop;
}

And to loop thru all the items:

for( var key in tst[rootKey] ) {
  for( var key1 in tst[rootKey][key] ) {
    console.log( "key:" + key1 + " --- Value:"+ tst[rootKey][key][key1] );
 }
}
