DeepL's API is accessible through all of the DeepL API plans. API plans were specifically created for developers and for anyone who wants to integrate DeepL’s REST API into their own products and platforms.
Our API documentation applies for all API plans.
DeepL API Developer allows developers to translate up to 1,000,000 characters in total. Once this limit is reached, it is not reset and you will need to upgrade to DeepL API Growth.
