Client libraries

The DeepL API's client libraries make it easier for developers to build DeepL-powered applications.

Client library features include but are not limited to:

• Out-of-the-box retries with exponential backoff for correct handling of 429 and 500 errors

• Persistent HTTP connection (keep-alive) enabled by default

• All document translation steps (upload, check status, and download) consolidated into a single convenience function

All officially supported client libraries, which you can find in the DeepL Github Organization, are open source under the MIT License.

We welcome feedback in the form of issues and pull requests!
