Example call

Sign in once with summer login; over HTTP, send Authorization: Bearer $SUMMER_TOKEN after export SUMMER_TOKEN=$(summer token) (sign-in). This job takes minutes. The CLI follows it and saves the file. Over HTTP the call answers running with a job id: check GET /v1/jobs/{id} until state is done (jobs); the quickstart has the full loop.
