Second attempt

    curl -H "X-ArchivesSpace-Session: $SESSION" \
        http://localhost:8089/agents/people?all_ids=true

This gives an array of integer ids. I haven’t created any “people” yet so I’m guessing that is the “Admin” account.

    [
      1
    ]

Trying

    curl -H "X-ArchivesSpace-Session: $SESSION" \
        http://localhost:8089/agents/people/1

I get back a big JSON blob like model-examples/admin-agent.json.
