This project contains an OpenAPI specification of the DeepL API, in YAML and JSON formats. There is also a simplified YAML with reduced descriptions that is embedded in our API documentation.
You can use this specification to explore the API in tools like Postman, or to auto-generate documentation, SDKs, and code libraries using tools such as Swagger Editor or OpenAPI Generator.
Note that Swagger's "Try it out" in-browser simulator creates valid Curl requests, the requests will fail due to CORS restrictions.
If you encounter issues while using this OpenAPI specification or have feature requests, please create an issue.
