Functions for receiving plugin data

Hi, I’m looking to add a section below our map that displays the same info as the map markers. Are there any built-in functions to retrieve the data from a marker e.g. the markers Action Content?

Also, I would like the search functionality to also search the Action Content. Currently our map markers are for individual businesses but we would like to be able to search for a country and return all the map markers from that country (which we have outlined in the Action Content).

Any help at all would be greatly appreciated ??
