通过 API 验证 Opensea NFT 所有权

Question

If I make an NFT purchasable on my store on opensea and somebody purchases that item, is there a way for me to build a website where somebody can retrieve services based on providing proof that they own the NFT that I sold on opensea?

Workflow

• I sell NFT x
• User y buys NFT x
• User y goes onto my website
• User y would like to use a service granted to them because they are the owner of NFT x
  • This is the crucial point, here I would like to verify that they really are the owner of the NFT

Does opensea provide any mechanism to make that verification possible via an API for example?

Answer 1

Check the opensea api docs -> asset model and than owner, this should work.

But for the prove you need them to sign with wallet, metamask?
