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

**Get VPS billing breakdown**

Return a billing breakdown for one VPS. Get `{id}` from `GET /api/v2/vps` `data[].id`. Pay-as-you-go Cloud VPS (`billing.isPayg: true`) return `kind: "payg_estimate"` — a max-24/7 monthly estimate with CPU, RAM, disk, and IPv4 line items (no account-level actuals; use `GET /api/v2/billing/metered-usage` for current-period PAYG charges). Fixed-cycle VPS return `kind: "fixed"` — the base plan price plus each paid add-on (extra bandwidth, storage, IPs). Every fixed amount is for the top-level `billingCycle`; monthly and annual duplicates are not emitted.
