Frequently asked questions

What is DeepL?

DeepL provides a translation API with a developer quickstart, API keys and official client-library examples.

Where should I start with a DeepL translation integration?

Use the DeepL API quickstart to obtain an API key and send a first translation request. Follow the documented endpoint and authentication setup for your API subscription rather than treating the consumer translation website as an API endpoint.

Provider source
Which DeepL API host should I use for a free API plan?

DeepL’s quickstart uses api-free.deepl.com for the free API plan instead of api.deepl.com. The translation example calls POST /v2/translate with an Authorization header using DeepL-Auth-Key and a JSON body containing text and target_lang.
