How to get activities of type from a block to a block

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 activities of type from a block to a block​

In order to get activities of type from a block to a block, Blocklens provides you a getActivitiesOfTypeFromBlockToBlock endpoint to do so.

Here you'll need parameters: coin_type, from_block, to_block.

Once you've obtained all the coin_type, 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.getActivitiesOfTypeFromBlockToBlock("0x1::aptos_coin::AptosCoin", {"from_block":18246150,"to_block":18246151});
  console.log(response);
};

runApis();

Step 3: Run the script​

ts-node index.ts
