How to get a block by 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 a block by hash​

In order to get a block by hash, Blocklens provides you a getBlockByHash endpoint to do so.

Here you'll need a parameter: block_hash.

Once you've obtained the block_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.APTOS_MAINNET.getBlockByHash("0x0517e1369f5159852973c47dc335d28b67ccffb238333542f880abc3fe3ab505");
  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_height": "53316416",
  "block_hash": "0x7e687b87fe8e8d2b8af953035e6aee2b570555720d9dd1344f2dfbd0f9dae93c",
  "block_time": "1970-01-01 08:00:00.000",
  "timestamp": "1683416298003828",
  "first_version": "136910820",
  "last_version": "136910820",
  "epoch": "136910820",
  "round": 0,
  "total_transactions": 0,
  "proposer": "0x48179547b95487f77214c12e2561d53531122a91e5f79ee9be968ce8185bc444"
