## GET /api/v2/vps/{id}/billing-breakdown

**Get PAYG VPS billing estimate**

Return a per-VPS max-24/7 monthly billing estimate for a pay-as-you-go Cloud VPS. Get `{id}` from `GET /api/v2/vps` `data[].id`, then call this only when `billing.isPayg: true`. The estimate includes CPU, RAM, disk, and IPv4 line items. It does not include account-level current-period actuals; use `GET /api/v2/billing/metered-usage` for current-period PAYG charges across all PAYG services.
