Cactal

Cactal Billing API

Read billing state and manage plans, site capacity, and prepaid usage balance. Every billing operation requires the organization owner role, which API keys cannot hold — today these operations are performed from the dashboard, return 403 for API-key callers, and are hidden from MCP tool lists.
