Using JSON API in postman

How to fetch data from a endpoint using json api specification in Postman

JSON Data:
[{“icu_beds”:“10”,“location”:“Chennai”,“oxygen_beds”:“10”,“id”:“101”,“normal_beds”:“10”,“hospital_name”:“Apollo”},{“icu_beds”:“21”,“location”:“Tirunelveli”,“oxygen_beds”:“23”,“id”:“102”,“normal_beds”:“23”,“hospital_name”:“Galaxy”}].

This is my json data. Is the format of the data correct or is there any rules or format to use json api?
