How can I get a list of cities in bitrix ajax request?

Question

PHP

Good afternoon, tell me, is it possible in 1C-Bitrix, somehow with an ajax request, without access to the admin panel and files, to get a list of cities? Those. if on such a request I get information about a specific city (more precisely, all matches found) /bitrix/components/bitrix/sale.ajax.locations/sear... , then how and what to make a request to get all available cities?
If anything, then here is the salezone.php module
