6. Error Response Body

Some non-answer responses MAY return entity bodies with information that could be more descriptive.

The basic structure of that response is an object class containing a REQUIRED error code number (corresponding to the HTTP response code) followed by an OPTIONAL string named "title" and an OPTIONAL array of strings named "description".

This is an example of the common response body.

{
  "errorCode": 418,
  "title": "Your Beverage Choice is Not Available",
  "description":
  [
    "I know coffee has more ummppphhh.",
    "Sorry, dude!"
  ]
}

This is an example of the common response body with an rdapConformance and notices data structures:

{
  "rdapConformance" :
  [
    "rdap_level_0"
  ],
  "notices" :
  [
    {
      "title" : "Beverage Policy",
      "description" :
      [
        "Beverages with caffeine for keeping horses awake."
      ],
      "links" :
      [
        {
          "value" : "https://example.net/ip/192.0.2.0/24",
          "rel" : "alternate",
          "type" : "text/html",
          "href" : "https://www.example.com/redaction_policy.html"
        }
      ]
    }
  ],
  "lang" : "en",
  "errorCode": 418,
  "title": "Your beverage choice is not available",
  "description":
  [
    "I know coffee has more ummppphhh.",
    "Sorry, dude!"
  ]
}
