WHOIS for .rio (nic.rio)

GEThttps://api.deepinfo.com/v1/lookup/whois

The WHOIS record of nic.rio, in the .rio registry's format.

TLD: .rio
Type: generic

.rio is a generic top-level domain.

The example requests the WHOIS record of nic.rio, the registry's own domain by convention, so the response shows the .rio registry's WHOIS format: compare raw, the text as the WHOIS server returned it, with parsed, the same record in Deepinfo's fields.
