WHOIS for .fi (nic.fi)

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

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

TLD: .fi
Type: country-code

.fi is the country-code top-level domain of Finland.

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