This data call provides information on objects that are stored in the RIPE DB. The result is aligned to a specific object, which is identified by an object type and an object key, which is similar to the Whois data call. In contrast to the Whois data call, this data call puts a focus on historical changes of an object and its related objects. Historical changes are given in the form of versions, one version - by default the latest version - is presented with details. Related objects are separated into referencing and referenced objects. Referencing objects are objects that have a reference to the object in focus and referenced objects are referenced from the object in focus.

Parameters
| Key | Value | Info | Required |
|---|---|---|---|
| resource | The resource to query. | This is a prefix (v4/v6), an AS number, or a string of the format "object-type:object-key" for looking up generic database objects. | yes |
| version | Defines the version to load details for. Can be provided as numerical value (e.g. version=4) or as time-based value (ISO8601 or Unix timestamp). | Given as a numerical value, the value must match exactly the historical version number. Given as a time-based value, the version that was valid at the given time will be returned. | no |
