Filtering Response

To save bandwidth and speed up response times, the Ipregistry API's fields parameter can be used to limit API results to a set of fields.

This parameter is supported by all API endpoints. To use this feature, append the fields parameter to your API request URL and specify as value the fields to return, separated by a comma.

The feature applies for JSON responses only.

Selecting a single field

For instance, returning connection information and its subfields:

Selecting multiple fields

Separate a series of fields with a comma:


Selecting a single nested field

Use the dot syntax to access a single nested field:


The dot syntax works for multi-level accesses:


Selecting multiple nested fields

You can combine the dot syntax and commas:


In the case you want to return several fields from the same level, use square brackets [ and ]:

Note that characters must be URL encoded before submitted. Characters %5B and %5D are respectively the encoded version of [ and ].

Excluding fields

In order to exclude fields, you need to prefix the field name with a minus sign -:


Since an empty fields value performs an empty selection, you may need to first select all fields before applying exclusions:


In case you exclude fields using the dot syntax, the exclusion applies to the last field.
