I am trying to deploy ERC 721 token and I am using ERC721PresetMinterPauserAutoId.sol preset in Remix and MetaMask. I am importing the preset and compiling and deploying (nto changing much in the process).
Now, I would like to connect it with a web app so that the web app can ask information like “who owns a particular token” and throw back result. I am however using API for the first time. I would like to use https://docs.openzeppelin.com/contracts/3.x/api/token/erc721 and fuctions like ownerOf(tokenId). For this, I need to specify the API endpoint, some https:// address that will be able to connect with the ethereum blockchain (or a testnet).
I would like to use API only one way (front-end asking the smart contract, not smart contract reaching to the external world through oracles).
Is there any guide or anything I can (as a beginner) use to guide me through these so that I can use the library of API calls OpenZeppelin provides and basically to set up everything for API connection with front-end?
Thank you for your help
