 Yes you can! There is a filter, `json_feed_item`, that allows you to modify the items in the feed just before they're inserted into the feed itself. For example, if you want to add a link to a post author's archive page to the respective item in the feed, you can use the following code:
 
-```php
+```
 function wp_custom_json_feed_fields( $feed_item, $post ){
-    $feed_item['author']['archive_link'] =  get_author_posts_url( $post->post_author );
+    $feed_item['author']['archive_link'] = get_author_posts_url( $post->post_author );
 
     return $feed_item;
