Hello. The status API endpoint only returns ‘reserved’ status for all premium .id domains. Example for foo.id:

Request:
https://domainr.p.mashape.com/v2/status?mashape-key=XXX&domain=foo.id

Response:
{
status: [
{
domain: ‘foo.id’,
zone: ‘id’,
status: ‘reserved’,
summary: ‘reserved’
}
]
}

However, according to Porkbun, Crazy Domains, Namecheap, Netim this is a premium domain available for purchase.
