> Hold a service upgrade for confirmation

- Group: services
- Tier: W
- Required scope: write:billing + write:services
- Docs: https://api.inleed.com/reference/services/upgrade-service

## Description

Validates the target type against the live upgrade options, then returns `{status:"confirmation_required", confirmationUrl, …}`. It charges nothing; on approval an unpaid proforma order is created and the plan changes only after it is paid.

## Path parameters

- `service` — string (required)

## Body

- `input` — string (required). A domain, email address, website URL, or Inleed service id — for example example.se, info@example.se or 42976. Resolved to the owning account automatically, and the resolved target is echoed back in the response.
- `service_type_id` — integer [default: 0]. The target plan's service-type id. Get it from get_upgrade_options → options[].serviceTypeId.
- `attempt_key` — string. Idempotency key for this intent. Keep it stable across retries so a timed-out retry cannot buy the same thing twice.

## Request
