## GET /api/v2/cdn/zones

**List CDN zones**

List CDN zones the caller can manage. Use this first when you only know the domain name and need the public `cdn_...` zone ID for detail, settings, or proxy-rule endpoints. Registrar-backed zones include `domainId`; DNS-only zones return `domainId: null`.

- `cursor` (query, string): Opaque cursor returned as `nextCursor` from the previous page. Example: `eyJsYXN0SWQiOiJjZG5fMDFoeGEzYjRjNWQ2ZTdmOGc5aDBqMWsybTMifQ`
