# NFT APIs Simple APIs to easily create [NFT Tokens](https://docs.nftyverse.com/apis/mint-nfts) and integrate [NFT Wallets](https://docs.nftyverse.com/apis/nft-wallets) natively for users in your app or website, without the need for any external plugins, browser extensions, embedded views or blockchain development. You are in full control of the [aesthetics and attributes](https://docs.nftyverse.com/metadata) of your NFT items. We currently support the most popular NFT formats (ERC-721 and ERC-115) on both the Ethereum blockchain as well as Polygon/MATIC support as well. Note: hosted NFT Wallets do not support non-NFT tokens or cryptocurrency at this time. [Earn additional revenue](https://docs.nftyverse.com/marketplaces) by taking a royalty fee on all secondary sales of your NFT Tokens. Our NFTs are compatible with huge 3rd party marketplace such as [OpenSea](https://opensea.io) and allow you to earn a royalty for sales on these compatible marketplaces.
