description: Goldman Sachs API surfaces (Marquee, Transaction Banking) do not publish numeric public rate
  limits. Limits are governed by the institutional client agreement, applied per service and per client
  account, and may differ between market-data feeds (high-frequency) and transaction-banking endpoints
  (lower-frequency, idempotent).
notes: Reconcile when Goldman Sachs publishes per-product rate-limit numbers.
