    Code example:

    function query_book_by_year($args, $request) {
    	if(isset($request["year"]) && intval($request["year"]) > 1500) {
    		$args['meta_key'] = 'year';
    		$args['meta_value'] = intval($request["year"]);
    	}		
    
    	return $args;
    }
    add_filter('rest_book_query', 'query_book_by_year', 10, 2);

    I wanted to see the SQL generated from the filters I’ve added. However, using &debug=sql on the http request parameter didn’t work for me.

    You can set a breakpoint at line 299 (at least at the time of writing) under class-wp-rest-posts-controller.php@get_items() method, which looks like this:

    $posts_query  = new WP_Query(); // line 298
    $query_result = $posts_query->query( $query_args ); // line 299
    

    Or if you don’t have a debugger setup yet, you can do:

    $posts_query  = new WP_Query();
    $query_result = $posts_query->query( $query_args );
    echo $posts_query->request;
    exit;
