How to get nft transfers by block number or hash

Prerequisites​

Before getting started, make sure you have the following ready:

  • Node v.14+
  • NPM

Step 1: Setup Blocklens​

First register your Blocklens account and get your Blocklens API Key.

Once you have your Blocklens API Key, install the Blocklens SDK in your project.

npm i blocklens-sdk

Step 2: Get NFT transfers by block number or hash​

In order to get nft transfers by block number or hash, Blocklens provides you a getNftTransfersByBlockNumberOrHash endpoint to do so.

Here you'll need a parameter: block_number_or_hash.

Once you've obtained the block_number_or_hash, you can copy the following code:

import Blocklens from "blocklens-sdk";

const blocklens = new Blocklens();
blocklens.init({ apiKey: "YOUR_API_KEY" });

const runApis = async () => {
  const response = await blocklens.ETH_MAINNET.getNftTransfersByBlockNumberOrHash("0x0517e1369f5159852973c47dc335d28b67ccffb238333542f880abc3fe3ab505");
  console.log(response);
};

runApis();

Step 3: Run the script​

ts-node index.ts
