Get docs/swagger JSON for single endpoint

I'm trying to get the docs for a single endpoint so I can generate a swagger client for just one of the services. Is there a way to do this? I tried /api/v2/api_docs/serviceName but it just returned the same JSON the top level did.

I'd also like to expose these docs for developers for each endpoint, rather than all of them.

Is there a way to do this?

Thanks,
Josiah
