public/get_risk_universes

Returns every risk universe (the isolated risk-containment boundaries trades never cross), each with its display name and description, its managers — at most one Standard (SM) and one Portfolio (PM2), each listing the derivative instruments it risk-prices and the collateral assets it accepts with their margin discounts and deposit metadata — and its Security Module. The one call that answers which universe and manager to choose: pick a universe, pick a manager in it, and pass its manager_id when depositing to a new subaccount (the accepted collateral entries carry the asset address for the deposit). The no-margin fallback universe (id 0) is included; it custodies dead-lettered deposits and lists no tradeable instruments. Public endpoint, no authentication required.
