Registration verdict (registered, likely_unregistered or unknown) with age and s
Registration verdict (registered, likely_unregistered or unknown) with age and status flags from registry RDAP, DNS, TLS, a look-alike similarity signal and an optional OFAC SDN address screen. Failed or throttled sources are unknown, never available. Not a guarantee of availability or safety; not legal advice. .dev and .app are not supported: a request with only those names is refused before payment; in a bulk batch they are removed before payment and the flat price still applies.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
