OpenAPI spec

Download the OpenAPI specification for the DeepL API

This repository contains an OpenAPI specification of the DeepL API in YAML and JSON formats.

File	Format	Description
openapi.yaml	YAML	Main REST API spec (source of truth)
openapi.json	JSON	Same content, auto-generated from YAML
voice.asyncapi.yaml	YAML	AsyncAPI spec for the streaming Voice API
voice.asyncapi.json	JSON	Same content, auto-generated from YAML

You can use these specs to explore the API in tools like Postman, or to auto-generate SDKs and code libraries using tools such as Swagger Editor or OpenAPI Generator.

Swagger’s “Try it out” in-browser simulator creates valid curl requests, but requests will fail due to CORS restrictions.

The spec files live in the api-reference/ directory of the api-docs repository. If you encounter issues or have feature requests, create an issue.
