# starknet\_getBlockWithTxHashes - STRK

Example code for the starknet\_getBlockWithTxHashes JSON-RPC method. Complete guide on how to use starknet\_getBlockWithTxHashes JSON-RPC in GetBlock Web3 documentation.

This method returns a block's header fields together with the list of transaction hashes it contains, given a block\_id. It is a lighter alternative to fetching full transactions.

## Parameters

| Parameter | Type   | Required | Description |
| --------- | ------ | -------- | ----------- |
| block\_id | object | string   | Yes         |

| id        | string | Request identifier matching the request                 |
| result    | object | Block header plus transaction hashes (see fields below) |

### Result Object

| Field          | Type   | Description                                                  |
| -------------- | ------ | ------------------------------------------------------------ |
| status         | string | Block acceptance status (ACCEPTED\_ON\_L2, ACCEPTED\_ON\_L1) |
| block\_hash    | string | Hash of the block                                            |
| l1\_gas\_price | object | L1 gas price in wei (ETH) and fri (STRK)                     |

## Use Cases

* **Lightweight Indexing**: List block transaction hashes without full bodies
* **Confirmation Status**: Read whether a block is ACCEPTED\_ON\_L1
* **Fee Tracking**: Read l1\_gas\_price per block
* **Explorer Backends**: Render block summaries
