Previously, I’ve added some code to my functions file:

// Create custom query for API
if( ! function_exists( 'product_meta_request_params' ) ) :
	function product_meta_request_params( $args, $request ){

        $args += array(
            'meta_key'		=> $request['meta_key'],
            'meta_value'	=> $request['meta_value'],
            'meta_query'	=> $request['meta_query'] == 1 ? array(
            array(
                "key"		=> "model",
                "value"		=> array(''),
				"compare"	=> 'NOT IN',
            )
        ) : $request['meta_query']
        );		
	
	    return $args;
	}
	add_filter( 'rest_product_query', 'product_meta_request_params', 99, 2 );
endif;

My API URL then looked like:
https://www.domain.com/wp-json/wp/v2/product/?page=' . $current_page . '&per_page=10&meta_query=1
