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.

pagination · object

Show Pagination

cursor · string | null

Cursor for the next page, or null on the last page.
