You can use two methods for adding the new meta field to Rest API. By using register_meta() function and register_rest_field() function.

You can use the register_rest_field() function to add additional meta key to the REST API
eg: 

add_action( 'rest_api_init', 'create_api_posts_meta_field' );
 
function create_api_posts_meta_field() {
 
    // register_rest_field ( 'name-of-post-type', 'name-of-field-to-return', array-of-callbacks-and-schema() )
    register_rest_field( 'post', 'banner_image', array(
           'get_callback'    => 'get_post_meta_for_api',

The form can be submitted to the browser by using button and input tag.
But we need to know which one is better for the form.

Diffrence between the <button type="submit"> and <input type="submit"> is,  Input type can hold only specified text inside the value attribute.
But the <button type="submit"></button> can hold any type of data, can add html content in the button tag, 

The button type is newer than input, so some older browser (eg: IE 6 ) dosn't support this tag.

In almost all modern browser will support button.
