# Get word trademarks

`GET https://api.unique.domains/v1/words/{word}/trademarks`

A word's trademark counts and its exact-match marks.

Live US and EU trademark counts with their classes, and up to 50 exact-match trademarks (live first, newest filing first) before the `office` and `status` filters. Zero live trademarks means no exact match was found, never that a name is safe.
