Description

Returns the block from the network based on the provided block number or hash. In addition to the transaction hashes included in the block, it also returns the full transaction objects.

Parameters

Response

BlockWithTransactions response object parameters

Example Request and Response

Prerequisite: You will need to install the Alchemy SDK before making requests with it.

The commands for installing it using npm or yarn are given below:

npm install alchemy-sdk

yarn add alchemy-sdk

Request

Here is an example of how to make a getBlockWithTransactions request using the Alchemy SDK:

// Imports the Alchemy SDK
const { Alchemy, Network } = require("alchemy-sdk");

// Configures the Alchemy SDK
const config = {
    apiKey: "alchemy-replit", // Replace with your API key
    network: Network.ETH_MAINNET, // Replace with your network
};

// Creates an Alchemy object instance with the config to use for making requests
const alchemy = new Alchemy(config);

const main = async () => {
    //Assign the hash to a variable
    let txHash = "0x92fc42b9642023f2ee2e88094df80ce87e15d91afa812fef383e6e5cd96e2ed3"

    //Call the method to return the block with transactions
    let response = await alchemy.core.getBlockWithTransactions(txHash)

    //Logging the response to the console
    console.log(response)
};

main();

Response
