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​

In order to get blocks from number to number, Blocklens provides you a getBlocksFromNumberToNumber endpoint to do so.

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.APTOS_MAINNET.getBlocksFromNumberToNumber({"from_block":18246150,"to_block":18246151});
  console.log(response);
};

runApis();

Step 3: Run the script​

ts-node index.ts

In your terminal, you should see the following JSON response with the data: In your terminal, you should see the following JSON response with the data blocks:

        "block_hash": "0x7e687b87fe8e8d2b8af953035e6aee2b570555720d9dd1344f2dfbd0f9dae93c",
        "block_time": "1970-01-01 08:00:00.000",
        "timestamp": "1683416298003828",
