# GameFi, Metaverse Xena and her friends are developing a Web3 game. Players are intended to buy and sell NFT items to improve their characters inside the game. With the AllPay widget, Xena can embed the NFT trading experience directly into the gameplay in a few easy steps and let the players buy/sell items to get ahead in the game. All you need to do is follow the instructions [here](/for-businesses/allpay-widget/quick-start/nft-widget-integration.md). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
