List all published landing pages in a landing page

Through API achieves this, but relevant APIs are only able to be called from backend instead of jQuery/AJAX.

Is there any approach to build a landing page which lists all published landing pages within automatically without external operation or data transmission?

@jh-anonymous,

Not sure but, wondering if this would get you part of the way?

Then, on the landing page be able to pul in the RSS feed?
