There is no single API, if any, to retrieve the serial number depending on the Solaris release, the hardware used and the optional packages installed.
Possible ways are sneep, prtdiag, smbios, ipmitool, ...
Therefore, I still think your software vendor is either asking for an hostid or just not enforcing the serial number binding.
Why not directly asking him about the zone case anyway ?
