Questions

Which baseUrl do I need?

The one matching your plan. A Free key on the Pro host is rejected as unauthorized, which looks like a bad key rather than a wrong host.

Translation is metered

DeepL counts characters against your plan. Document translation counts the whole document, not just what changed.

Is my key stored on the hub?

Never. It lives only in your own Windmill workspace, encrypted at rest.
