Add balance field to BaseNft

[donutdaniel]

Seems like the balance field returns when possible on a BaseNft object, through both the getNFTs call (with or without metadata). This is useful for determining the amount of the tokenId when referencing an erc1155.

Adding this type makes it so that typescript does not throw errors.

Btw, is there a difference between v1 and v2 api?

. Current documentation on https://docs.alchemy.com/alchemy/enhanced-apis/nft-api/getnfts references v2.

Thanks for this useful library!

Thanks for noticing and including the fix! The balance field will always be populated in the response and isn't optional. Can you please update that?

There is no difference between the v1 and v2 versions of the NFT API. We ended up bumping up the version since all of the other endpoints were already on v2.

I left it as optional since an erroneous response will omit the balance field. Thoughts? Can certainly make the change though

@donutdaniel This actually a bug, and the balance field should always be included in the return. The backend team is working on a fix in the meantime. Thanks for catching, and can you please make the field required?

Gotcha, just updated. Thanks for the quick turnaround!

thanks for your contribution! Will have a new release out in the coming week or two
