Also returns any of the rules of the default rule sets, which are shared: their IDs are what a card limit's `ruleIds` holds after you create it with a set's name. Send `x-environment: LIVE` for a production rule. Any member of the organization can read it. ## OpenAPI ````yaml /api-reference/banking.openapi.json get /realms/{realmId}/organizations/{organizationId}/accounts/{accountId}/card-limit-rule/{cardLimitRuleId} openapi: 3.0.3 info: title: Banking version: 1.0.0 description: >- Portão 3 banking API. Every endpoint requires a bearer token in the Authorization header (Authorization: Bearer ) unless its page states otherwise; see the Authentication guide. That requirement is not repeated per endpoint. Generated by tools/openapi from code (routes + security) and the hand-written spec (request/response bodies). Banking attaches a zod validationSchema at the route; request bodies are resolved from it (object + array roots). Responses have no presenter layer, so they stay tier=unknown.
