## GET /api/v2/domains/{id}/nameservers

**Get domain nameservers**

Return current nameservers plus action gates for changing them. Get `{id}` from `GET /api/v2/domains` `data[].id`. `actions.canChangeNameservers.allowed` is false during transfer, pending/suspended states, or when a registry-lock unlock flow is required. If `registrarLock.unlockAction` is non-null, call that action before changing nameservers. `dnssecAutoWillBeBlocked` is the server-composed warning for automatic DNSSEC: when true, a nameserver update will pause DNSSEC automation for the 72-hour cooldown window. HostUp-managed delegation normally uses `primary.ns.hostup.se` and `secondary.ns.hostup.se`; when automatic DNSSEC is active on that delegation, callers should prefer `/api/v2/domains/{id}/dnssec-auto` over manual DS/KEY writes.
