Tollbooth Sample

Weather from Open-Meteo: current conditions, multi-day forecast, and historical data for a location and date range.

It is genuinely useful, and it is also the reference implementation. Tollbooth Sample is the canonical Operator — the one to read when you want to see how the whole pattern fits together, from npub proofs and the Secure Courier through pricing models to Lightning settlement, without the domain logic of a real business in the way.

If you are building an Operator of your own, start here. Every other service in the fleet is this shape with different tools bolted on.
