How to get blocks from number to number

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 blocks from number to number​

Here you'll need parameters: from_block, to_block.

Once you've obtained all the from_block, to_block, 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.getBlockToBlock({"from_block":18246150,"to_block":18246151});
  console.log(response);
};

runApis();

Step 3: Run the script​

ts-node index.ts
