Overview

Lists Vienna classification design codes used to describe figurative elements in trademarks. Filter by depth (1 = category, 2 = division, 3 = section) or search descriptions. Use this to build Vienna code pickers.

Query Parameters

q
string
Substring search across descriptions (case-insensitive, max 200 chars).
depth
integer
Filter by depth: 1 (category), 2 (division), or 3 (section).
category
string
Two-digit category code filter (e.g. 03).
limit
integer
default:"100"
Max results (1-500).
cursor
string
Pagination cursor (the code of the last item returned).

Response

This endpoint is publicly cacheable, so the response never includes request_id.
object
string
Always list.
data
object[]
Array of Vienna code records ordered by code.
data[].code
string
Vienna code (e.g. 03, 03.05, 03.05.01).
data[].object
string
Always design_code.
data[].category
string
Two-digit category code (e.g. 03).
data[].division
string | null
Division-level code (e.g. 03.05). null for depth-1 codes.
data[].section
string | null
Section-level code (e.g. 03.05.01). null for depth-1 and depth-2 codes.
data[].depth
integer
Depth (1, 2, or 3).
data[].description
string
Description text.
has_more
boolean
Whether more pages are available.
