Questions about this workflow
What counts as the best offer?
Notis asks OpenSea for the best offers on that NFT, which is the strongest current bid to buy it.
Which cells does it watch?
You point Notis at an A1 range, and it watches exactly those cells for changes.
Can it also fetch the best listing?
Yes. You can ask Notis to report both the best offer and best listing in the same run if you want a full picture.
