An Artifact of yours that anyone with the link can open can now carry a price, from $3.99 to $999. Choose Sell beside Share in the title menu, set the price, and anyone who opens the link sees the title, the poster and a Buy button. They pay once by card and the page opens in place; the purchase stays theirs even if you later change or remove the price.
Set up payouts first, from your account page, and the sale pays out to your bank through Stripe. You keep 90% less the card fee: $3.17 of a $3.99 sale. A refund takes back your share of that sale in proportion.
