Fetching batch results with `request_id`

[m-sanders]

The documentation mentions:

Responds with a 202 Accepted if successful. That means the server accepted the request and queued it for processing. The response includes a list of unique request_ids that can be used to check the status of the request later on.

However, there doesn't appear to be an exposed endpoint to lookup a result on the request_id. Am I missing something?
