Retrieves the status and result of an analytics job created when any supported analytics endpoint is called with async=true. Poll this endpoint until the job reaches a terminal state (DONE or FAILED).

The job status moves through the following states: PENDING while the job is running, DONE when the result is ready, and FAILED if the job could not be completed. Poll every few seconds until a terminal state is reached. Large Books may take longer to process.

When the status is DONE, the response includes a result_url, a temporary pre-signed download link to retrieve the analytics payload, which is identical in shape to the corresponding synchronous endpoint's response. The job and its result_url are valid for 24 hours from the time the job was created.
