Ok. Nostr.band actually has an endpoint that is EXACTLY what I want
stats.nostr.band/stats_api?method=stats&options=
Reviewing the Terms though it's unclear if there'd be a problem using it. Intent is non commercial as both viewing a user owning and viewing a block clock locally or running Nodeyez is personal, but if either were used in a public setting (e.g at an Xpub bar serving drinks) that may be commercial. Of course I as a coder can't control what people do with the tools.
Who runs nostr.band?
