So, you've just bumped the REST vs SOAP conundrum. =)

There is no practical way to generate a WSDL description for a REST service.

But again, there is not really a good reason to do that, since they're consumed differently.

Your options are:

• explain to the developer who will use your web service that this is a REST service (and not SOAP)
• write a SOAP version of your service

In either case, you want to document and possibly give examples on how to consume the service. FastAPI already helps to do that with the /docs page, but you may need to better document how it's supposed to be used.

Good luck!
