I wrote a simple bot which is posting activities from https://raretoshi.com to Nostr.
I appreciate some follows if you want to support bitcoin artists (and devs :D)!
For best UX I recommend using Coracle. The images are attached as base64 I think some nostr clients do not support that.
There is also a Toshi Search page linked in the bot profile description which you can use to browse stats from raretoshi (or other platforms using tokenocean).
