E-commerce related fields not showing in CMS collection items API

I fetch all items of products from E commerce section but it’s not giving me the e-commerce related API

{
   "shippable":true,
   "tax-category":"standard-taxable",
   "_archived":false,
   "_draft":false,
   "ec-product-type":"b6ccc1830db4b1babeb06a9ac5f6dd76",
   "name":"Plain Shirt",
   "slug":"plain-shirt",
   "updated-on":"2020-08-11T08:07:12.584Z",
   "updated-by":"Person_5e8a9c31fbc2c0b817dc5b36",
   "created-on":"2020-08-11T06:38:27.284Z",
   "created-by":"Person_5e8a9c31fbc2c0b817dc5b36",
   "published-on":"2020-08-11T08:08:31.359Z",
   "published-by":"Person_5e8a9c31fbc2c0b817dc5b36",
   "default-sku":"5f323ce35db75ea7720849a8",
   "category":[
      "5f32516d2ff3d073afc7a451"
   ],
   "_cid":"5f313689d95c7cefba81ede4",
   "_id":"5f323ce34398d36bd2333e58"
},

It seem to be missing all the other fields I mentioned like Price and Media
