## GET /api/v2/shared-hosting/{accountId}/domains

**List hosting domains**

Return all domains attached to a shared-hosting account in one typed array. `kind` tells whether each entry is the main domain, addon domain, parked domain, or subdomain; use `actions.canAddAddon` before adding another addon domain. On legacy HostUp control-panel accounts, the read may only know the main domain and `actions.canAddAddon.allowed` is false with guidance to use the control panel SSO link manually or contact support for migration.
