Retrieve languages
API reference for retrieving supported languages with the DeepL API.
Get all currently supported source and target languages that can be used for text and document translation.
As of January 2024, Arabic (AR) is supported as a source and target language for text translation, but it is not yet supported for document translation. Therefore, Arabic has not yet been added to the /languages endpoint. We will add Arabic to the /languages endpoint after document translation support is added.
To get languages available for glossaries, please see here.
We also provide a spec that is auto-generated from DeepL's OpenAPI file. You can find it here.
The example below uses our API Pro endpoint https://api.deepl.com. If you're an API Free user, remember to update your requests to use https://api-free.deepl.com instead.
Example request: supported target languages
curl -X GET 'https://api.deepl.com/v2/languages?type=target' \
