How to get transaction payloads from time to time

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 transaction payloads from time to time​

In order to get transaction payloads from time to time, Blocklens provides you a getTransactionPayloadFromTimeToTime endpoint to do so.

Here you'll need parameters: from_time, to_time.

Once you've obtained all the from_time, to_time, 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.getTransactionPayloadFromTimeToTime({"from_time":"1696048259","to_time":"1696048260"});
  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:
