I’m slightly behind on what’s possible with lightning.

Is it possible to setup something like a lightning address, that’s reusable (like bank details) for a service provider?

Then someone can sent you a payment (like a Nostr Zap). They get a unique receipt that only they should know.

Then they can provide that receipt to the service provider and say I have pre-paid this request.

Basically looking for a single request API remote Nostr event POW service, where someone sends partial event, difficultly target and a pre-payment hash that can be verified by the service provider as unspent yet.
