getBlock

How to use it

// Import required libraries and modules from Tatum SDK
import { TatumSDK, AlgorandIndexer, Network } from '@tatumio/tatum';

// Initialize the Tatum SDK
const tatum = await TatumSDK.init<AlgorandIndexer>({ network: Network.ALGORAND_INDEXER });

// Define the input parameters as a dictionary object
const params = {
    roundNumber: 1000,  // Specify the round number (integer) for which you want to lookup the block.
    headerOnly: true    // Optional: Set to true to retrieve only the block header without transactions (boolean).
};

// Lookup the block for the specified round number
const blockInfo = await tatum.rpc.getBlock(params);

// Log the block information
console.log('Block Information:', blockInfo);

// Always destroy the Tatum SDK instance when done to stop any background processes
await tatum.destroy();

Overview

The getBlock method allows you to lookup a block by specifying its round number. You can retrieve both the block header and transactions, or only the block header using the headerOnly flag.

Request Parameters

The method requires the following parameters:

• roundNumber (number, required): Specify the round number for which you want to lookup the block.
• headerOnly (boolean, optional): Set to true to retrieve only the block header without transactions (boolean).

Return Object

The method returns information about the specified block, which includes details such as the block's round number, timestamp, previous block ID, seed, transactions, and more. If the headerOnly flag is set to true, the returned object will contain only the block header information.

Please note that the structure of the returned object may change in different RPC versions.
