Getting child tables with REST API?

I’m trying to use the REST API to query Events (such as calls, meetings, etc.) that are linked to other records.

I need to build a list of Events and the documents they’re linked to, not just get them one at a time.

The problem is that since the linked doctypes are in child tables, they aren’t returned when using a GET on Events.

For example: url.com/api/method/frappe.client.get_list? doctype:event will return all of the events and their details, but it won’t show the documents they’re linked to.

Does anybody know of a way to do this?

If I need to pay somebody to build a method hat can do it, I’d gladly pay them for their time, and contribute it back to the community.
