Fern supports a variety of OpenRPC extensions that enhance your API specification and generate higher-quality SDKs.
You can apply these extensions in two ways: by overlaying them in separate override files or by embedding them directly in your OpenRPC specification. See Overrides for more information.
The table below shows all available extensions and links to detailed documentation for each one.
If there’s an extension you want that doesn’t already exist, file an issue to start a discussion about it.
