Translate API looks up a word in a dictionary and returns all translations ordered by frequency. The API translates from and to German for the following languages: English, Spanish, Dutch, Polish, Italian, and Czech. Translate API allows to filter by word class and by minimum frequency.

Test the API

You can test the API and develop your own application with our test translate API – for free.

Test the test API with:

  • langpair: de-en
  • query: Anzahl
  • wortart: VERB (optional)

http request
wget ""

Important note (!)::
The initial API call might take up to 15 seconds because the heroku dyno falls asleep after 30 minutes of inactivity.
(The test API runs on a free heroku dyno.)

Further limits of the test API
The test API contains only a subset of the complete dictionary database. Therefore only high frequent words are included.
E.g.: change, cover and make are high frequent words.

API response

l1_text: german word
l2_text: translation of the german word
wortart: word class (NOMEN (=noun), ADJ, VERB, ADVERB)
synonyme1: „Synonyms“ for the translation of the German word, created by collecting the alternative translations. For instance, the words car, auto, automobile, motor vehicle, motorcar are all translations of the German word Auto and thus can be regarded as „synonyms“.
synomyme2: „Synonyms“ for the German word, created by collecting alternative translations of the translation of the German word.
freq: The number specifies how often the translation was used in our database of translated documents. The higher the number the more common the translation.
Note: Since there is always noise in the dictionary sources as well as in the translated documents, in order to make sure that you only get correct translations you can set the query parameter min_freq (minimum frequency) to 1 to get only translations that have occurred at least once in our corpus. Compare the result of the two api calls with and without min_freq:

Without min_freq:

With min_freq = 15000:
