# Money safety: dry run, confirm, idempotency

Creating a server places an order and pays it from your **account balance** — never from a stored card.

1. Ask for a quote: `"dry_run": true`. Nothing is created.
2. Order with `"confirm": true` and an `Idempotency-Key` header (a UUID per logical order).
3. Network error? Retry with the **same** key and body: you get the first answer back (`Idempotency-Replayed: true`), never a second server.

Destructive actions (`rebuild`, `reset`, snapshot restore, delete) also need `confirm`.
One-time root passwords are only returned on requests **without** an Idempotency-Key, because replayable answers are stored.
