How to get NFT transfer value using Achemy API

Question

We are using getAssetTransfer to get all the transfers from and to a wallet for a specific NFT contract, similar to this https://docs.alchemy.com/docs/how-to-get-the-transfer-history-of-an-nft.

We are trying to figure out how to get the value of each transfer as the getAssetTransfer returns value: null for erc-721. It can be done by getting the relevant transaction of the transfer but we run into an issue when there are multiple transfers from the same transactions so we can identify the value of each transfer. How can this be done using the Alchemy API?

Answer 1

You are on the right track with using the getAssetTransfer API endpoint.

However, it only returns information about the transfer of an asset, such as an NFT, on Ethereum, but it does not include the value of the transfer.

This is because the value of an NFT transfer is not stored on the blockchain, so it is not possible to retrieve it directly using an API like Alchemy. Therefore you will need to use a third party that records the value of the NFTs transfers.

You can try to use a NFT marketplace's API, such as the Opensea API to fetch the value of a specific NFT.

They have an enpoint called getAsset, so you can retrieve metadat information about the NFT, including the current price, sale history, etc.

I hope this helps!
