Auth:  export PRESEEM_KEY=<api key>  (HTTP Basic, key as username, empty password)

Resources (read-only):
  accounts   list | get <id>
  ap         list | get <id>            (access points)
  ap-config  get  <id>

  routers    list | get <id>
  olts       list | get <id>
  sites      list | get <id>

Write operations:
  clear-services  [--dry-run | --confirm] [--account <id>]
                  delete all services (MACs) from all accounts
                  --dry-run: preview only; --confirm: actually delete
                  --account: limit to a single account ID

Common flags:
  list:  [--json] [--page N] [--limit 100..1000]
         (no --page = auto-paginate; --json + auto = merged data envelope)
  get:   [--json]

Examples:
  preseem accounts list
  preseem ap list --json | jq '.data[].name'
  preseem ap get 123
  preseem ap-scores
  preseem sites list --page 1 --limit 100
