I looked into this, and I initially thought that you can use Devices API under Google Cloud Identity to check for Device Information that is installed with Endpoint Verification. But after doing further research regarding its REST Resources provided below:
JSON representation
{
"name": string,
"createTime": string,
"lastSyncTime": string,
"ownerType": enum (DeviceOwnership),
"model": string,
"osVersion": string,
"deviceType": enum (DeviceType),
"serialNumber": string,
"assetTag": string,
"imei": string,
"meid": string,
"wifiMacAddresses": [
string
],
"networkOperator": string,
"manufacturer": string,
"releaseVersion": string,
"brand": string,
"buildNumber": string,
"kernelVersion": string,
"basebandVersion": string,
"enabledDeveloperOptions": boolean,
"otherAccounts": [
string
],
"enabledUsbDebugging": boolean,
"securityPatchTime": string,
"bootloaderVersion": string,
"encryptionState": enum (EncryptionState),
"androidSpecificAttributes": {
object (AndroidAttributes)
},
"managementState": enum (ManagementState),
"compromisedState": enum (CompromisedState),
"endpointVerificationSpecificAttributes": {
object (EndpointVerificationSpecificAttributes)
}
}
It seems that the host name information is currently not available. So I would suggest you could submit it as a feature request here
