Is there any way to get openapi/swagger specs for ZohoCRM REST API?

Is there any way to get openapi/swagger specs for ZohoCRM REST API?

I'm working on project written in language (golang) which is not among supported languages. 

Since REST API is basically set of CRUD operations it'd be really great to have openapi/swagger specs to be able to generate at least basic client. 

Is there any way to get it?
