RDAP JSON Response Structure (RFC 9083)

Object types

Responses may include domain, nameserver, entity, IP network, or autnum objects. Domain lookups often return linked entities and nameservers.

Important fields

• ldhName / unicodeName: ASCII and Unicode forms.
• status: standardized lifecycle flags.
• events: registration, expiration, last changed.
• nameservers: authoritative DNS hosts.
• entities: registrant/admin/tech/abuse as vcardArray.

vcardArray

Contact data uses jCard (RFC 6350). Parse vcardArray[1] tuples and expect redacted placeholders.

{
  "objectClassName": "domain",
  "ldhName": "example.com",
  "status": ["client transfer prohibited"],
  "events": [{"eventAction": "registration", "eventDate": "1995-08-14T04:00:00Z"}]
}

Tips

Read notices for authority/redaction. Follow links with rel=related for registrar referrals on thin registries.
