This API endpoint is designed for minting NFTs straight into a user's wallet. Ideal for selling NFTs, targeted airdrops, or minting collectibles. Supports both custom Mintable Wallets and standard crypto wallets. Note: If you don't pass in a metadata object - it will create a random NFT using your pre-mint data you've set up on the self serve dashboard. But if you pass in a metadata object, it will mint a new NFT with the new metadata object you passed in. Note: Keeping 'mint' and 'claim' endpoints separate simplifies analytics, making it easier to track each call's specific purpose.
