notes: Every account is assigned a single API token used in place of username/password. REST accepts the token either
  directly in the URL (?token=...) or in the Authorization header formatted as 'Token <token>'. WebSocket subscribe/unsubscribe
  requests carry the token in the 'authorization' field of the JSON payload. Token rotation is available on the
  account Token page (announced in the 2026-05-12 changelog). No OAuth surface.
