# eth_getTransactionByBlockHashAndIndex | Monad

> Monad API method that returns information about a transaction by block hash and transaction index position. Chainstack Monad reference.

Monad API method that returns information about a transaction by block hash and transaction index position. This method allows you to retrieve a specific transaction from a block when you know both the block hash and the transaction's position within that block.

## Parameters

* `data` — the 32-byte hash of the block.
* `quantity` — the transaction index position within the block, encoded as hexadecimal.

## Response

* `result` — the transaction object, or `null` when no transaction was found:
  * `blockHash` — hash of the block containing this transaction
  * `blockNumber` — number of the block containing this transaction
  * `from` — address of the sender
  * `gas` — gas provided by the sender
  * `gasPrice` — gas price in wei
  * `hash` — hash of the transaction
  * `input` — the data sent along with the transaction
  * `nonce` — number of transactions made by the sender
  * `to` — address of the receiver
  * `transactionIndex` — integer of the transaction's index position
  * `value` — value transferred in wei
  * `v`, `r`, `s` — signature values

## `eth_getTransactionByBlockHashAndIndex` code examples

<CodeGroup>
  ```javascript ethers.js theme={"system"}
  const { ethers } = require("ethers");

  const provider = new ethers.JsonRpcProvider("CHAINSTACK_NODE_URL");

  async function getTransactionByIndex() {
    const blockHash = "0xf3cf930f1b4d9637134d09f126c57c30c3f4f40edf10ba502486b26d14b4f944";
    const index = "0x0"; // First transaction
    const tx = await provider.send("eth_getTransactionByBlockHashAndIndex", [blockHash, index]);
    console.log(tx);
  }

  getTransactionByIndex();
  ```

  ```python web3.py theme={"system"}
  from web3 import Web3

  node_url = "CHAINSTACK_NODE_URL"

  web3 = Web3(Web3.HTTPProvider(node_url))
  block_hash = "0xf3cf930f1b4d9637134d09f126c57c30c3f4f40edf10ba502486b26d14b4f944"
  tx = web3.eth.get_transaction_by_block(block_hash, 0)
  print(tx)
  ```

## Use case

A practical use case for `eth_getTransactionByBlockHashAndIndex` is iterating through all transactions in a block when analyzing block contents, or retrieving specific transactions based on their execution order.
