Is there a http end point to get expression variables?

[phill-85]

The url "/settings/protocols" on the companion instance shows how to (http)get a custom variable, is there a comparable method for expression variables?

Whilst I'm here is there a websocket end point?

You can get those through /api/variable/expression/<name>/value. You can actually do the same for custom-variables, it just made sense to add the explicit endpoint for custom variables to match the set endpoint

No. Either poll, or I think the ember+ api can do subscriptions
