Endpoint support

This is to go along with https://github.com/my-koop/service.website/pull/186. I added a couple of example endpoints (although not used here) to show what's possible. These will be moved to https://github.com/my-koop/module.base shortly.
I just recalled I wanted to change them to TypeScript but it was late last night, I'll do it as part of the CR fixes.
