post/domain-risk/v1/parked1 credit

Detect whether a domain is parked or listed for sale. Checks parking nameserver signals and the domain's root page for for-sale phrases and marketplace redirect hosts (Sedo, Afternic, GoDaddy, etc.). Returns a confidence-scored verdict: parked, for_sale, or actively in use. Returns 'unknown' when the page cannot be read.

Working example
Parameters

A full domain to evaluate (e.g. example.com, secure-login.io). A bare host, full URL, leading www., or an IDN (münchen.de) are accepted and normalized to its registrable form.
