Is this possible to get the Hue Saturation adjustment Layer value using the Photoshop API?

It is not in DOM API yet and probably won’t be for a while.
There was a change in the recent version of Photoshop. So using action manager code / batchPlay …you have to take it from different place in different format.

const {executeAsModal} = require("photoshop").core;
const {batchPlay} = require("photoshop").action;

async function actionCommands() {
   const result = await batchPlay(
      [
         {
            _obj: "get",
            _target: [
               {
                  _property: "adjustment"
               },
               {
                  _ref: "layer",
                  _id: 2 // change this
               },
               {
                  _ref: "document",
                  _id: 59 // change this
               }
            ],
            _options: {
               dialogOptions: "dontDisplay"
            }
         }
      ],
      {}
   );
   
   const pinned = result[0].adjustment[0].adjustment[0].hue;
}

async function runModalFunction() {
   await executeAsModal(actionCommands, {"commandName": "Action Commands"});
}

await runModalFunction();
