 Hi @millerf01, welcome back and thank you for the ticket!

 You were almost there, just mismatched the post types: need to use
 `attachment` instead of `media`.
 The `apiFetch(...)` request is correct, only `meta_key` registration needs
 some polish.

 There are two options for that:
 {{{#!php
 <?php
 register_meta( 'post', 'some_data', array(
         'object_subtype' => 'attachment',
         'type'           => 'string',
         'description'    => 'Some data',
         'single'         => true,
         'show_in_rest'   => true
 ) );
 }}}


 or

 {{{#!php
 <?php
 register_post_meta( 'attachment', 'some_data', array(
         'type'         => 'string',
         'description'  => 'Some data',
         'single'       => true,
         'show_in_rest' => true
 ) );
 }}}
