Hi,

Did you mean querying posts by custom fields?

If so, please try this code:
```
add_filter( 'rest_{type}_query', function( $args ) {
    $args['meta_query'] = array(
        array(
            'key'   => 'my_field',
            'value' => esc_sql( $_GET['field'] ),
        )
    );

    return $args;
} );
```
REST URL:
```
http://site.com/wp-json/wp/v2/posts?field=test
```
The wildcard {type} can be: post | user | comment | attachment | custom post type | taxonomy.
