How to get transactions by type
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 transactions by type
In order to get transactions by type, Blocklens provides you a getTransactionsByType endpoint to do so.
Here you'll need a parameter: type.
Once you've obtained the type, 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.getTransactionsByType("block_metadata_transaction");
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:
