How to get the link table data in GET /record API

Hi team

i need to know for example you created a table and in that table you have some fields as record selector and one of the entry is linked with other table
In the API response i am getting only the record ID how can i get the full info corresponding to that record , i want a single API to get all this details

There is no single API, you need to do a recordRead to resolve recordID values.
