Yes, without linking to a specific client, with a neutral visualization like njump.me

It would be cool if you also expose a relay with search capabilities (https://github.com/nostr-protocol/nips/blob/master/50.md).

One more, maybe crazy idea: this search relay could also return generic web results* through notes generated and signed by Kagi, so users could search the web within their preferred Nostr client, share and comment results.
Of course this would give Kagi a nice visibility.

* Only when the filter set Kagi as author.
