Preview DNS records from a zone file

POST /api/v2/dns-zones/{id}/smartcopy-zonefile

Parse a pasted DNS zone file and compare its importable records with the selected HostUp DNS zone.

Get {id} from GET /api/v2/dns-zones data[].id.

The zone file is limited to 200,000 characters.

Invalid or unsupported rows are skipped; the request fails when no valid records remain.

This operation only builds a preview and does not change the zone.

Validation failures use errors[] with the /zoneFile pointer and a stable field code.
