Notes

• Pass a domain name or an IPv4 / IPv6 address in q. Schemes, paths and a leading www. are stripped for you.
• Answers are cached for a few hours. cached_age_seconds tells you how old the record is.
• Fields come from the registry, so the set varies by top level domain. Anything unmapped stays in the raw record on the web page.
• Errors return HTTP 400 with {"ok": false, "error": "..."}.
• Please keep it to a few requests a minute per client. Bursts are rate limited.
