Comment (by Dudo):

 Hi, thank you for your response.

 It is very simple:

 {{{#!php
 <?php
 add_action( 'rest_api_init', 'yasr_rest_comment_meta' );

 function yasr_rest_comment_meta() {

         register_rest_field(
                 'post',
                 'yasr_overall_rating',
                 array(
                         'get_callback' => 'yasr_rest_get_overall_rating',
                         'update_callback' => null,
                         'schema' => null,
                 )

         );

 }

 function yasr_rest_get_overall_rating () {

         $overall_rating = yasr_get_overall_rating();

         return $overall_rating;

 }

 }}}
