Hey nostr, you’re smart. Is there a way I could broadcast a note offering a video for sale. The note would contain all of the metadata about the video but the .mp4 url itself would be encrypted (or else someone could take it without paying) I would want it to be a flat price and would want there to be no interaction required for someone to pay for the video (perhaps by zapping the note) and then receive the decryption key to decrypt the url?

I think it could be possible with lnurl LUD-10 success action potentially if the seller pregenerates a preimage that acts as the encryption key for the url in the note?
