How can we let the Dapp read other Nfts (from other smart contract) and Sell them? Like a real marketplace does

I just wanted to know how can we sell other Nfts not created by us or from the contract we have created.

To accomplish that, you will need to utilize a third-party API service. These services specialize in creating a comprehensive database of all NFTs from a specific blockchain. This is the only method available to achieve this goal. There are several API providers you can consider, such as OpenSea and Moralis, among others.
