Add a counterparty or instrument to a restricted (MNPI) list

POST 
/api/v1/admin/restricted-lists

Creates a DENY entitlement grant for the COUNTERPARTY or INSTRUMENT dimension. The resource is blocked across all books for the grant's principal (typically a firm-wide or desk GROUP). To grant a wall-crossing exception for a single user, create a USER-principal ALLOW grant for the same resource via POST /api/v1/admin/entitlements with effect=ALLOW, reason, and valid_until.
