Roughly speaking:
WSDL is to XML web services as OpenAPI is to REST
They both model the API and message structure of an API. AFAICT WSDL goes a little farther in that you can declare message sequences (I might be giving short shrift to OpenAPI here).

little bit off-topic, but do anybody know of something similar for soap/wsdl? I'm aware of soapui mock service.
Doesn't wsdl just expose the schema on the server?
WSDL and OpenAPI/Swagger solve similar problems.

Short of “this requires oauth” I think you are right about openapi
