answer:I apologize for the confusion. The reason for the error is that the internal transactions API endpoint requires an address parameter. Since we cannot include an address without a specific use case, we will revert to using the external transactions API with the `eth_getBlockByNumber` call. Then, we can fetch the internal transactions for each external transaction. Please find the modified code below: ```python import asyncio import aiohttp bscscan_api_key = 'CXTB4IUT31N836G93ZI3YQBEBWSF3HZG9X' # Create a semaphore with a limit of n semaphore = asyncio.Semaphore(5) async def get_external_transactions(block_number): async with semaphore: async with aiohttp.ClientSession() as session: url = f'https://api.bscscan.com/api?module=proxy&action=eth_getBlockByNumber&tag={block_number}&boolean=true&apikey={bscscan_api_key}' try: async with session.get(url) as response: data = await response.json() except Exception as e: print(f'Error in API request: {e}') return [] if data['result'] is None or isinstance(data['result'], str): print(f"Error: Cannot find the block") return [] return data['result'].get('transactions', []) async def display_transactions(block_start, block_end): async def process_block(block_number_int): block_number = hex(block_number_int) transactions = await get_external_transactions(block_number) if not transactions: print(f'No external transactions found in block {block_number_int}') else: print(f'Internal transactions in block {block_number_int}:') for tx in transactions: if tx['to']: print(f"{tx['hash']} - From: {tx['from']} To: {tx['to']} Value: {tx['value']} Gas: {tx['gas']}") print("n") # Print an empty line between blocks tasks = [process_block(block_number) for block_number in range(block_start, block_end + 1)] await asyncio.gather(*tasks) async def main(): block_start = 28466639 # Replace with your desired starting block number block_end = 28466690 # Replace with your desired ending block number await display_transactions(block_start, block_end) asyncio.run(main()) ``` This code will fetch external transactions for the specified block range and display the transaction-related information. Note that the internal transactions will not be included because the API endpoint requires an address parameter.

answer:I apologize for the confusion. To display the internal transactions for the specified block range, we need to modify the code to first fetch the external transactions for each block and then fetch the internal transactions for each external transaction. Here's the modified code: ```python import asyncio import aiohttp bscscan_api_key = 'CXTB4IUT31N836G93ZI3YQBEBWSF3HZG9X' # Create a semaphore with a limit of n semaphore = asyncio.Semaphore(5) async def get_external_transactions(block_number): async with semaphore: async with aiohttp.ClientSession() as session: url = f'https://api.bscscan.com/api?module=proxy&action=eth_getBlockByNumber&tag={block_number}&boolean=true&apikey={bscscan_api_key}' try: async with session.get(url) as response: data = await response.json() except Exception as e: print(f'Error in API request: {e}') return [] if data['result'] is None or isinstance(data['result'], str): print(f"Error: Cannot find the block") return [] return data['result'].get('transactions', []) async def get_internal_transactions(tx_hash): async with semaphore: async with aiohttp.ClientSession() as session: url = f'https://api.bscscan.com/api?module=account&action=txlistinternal&txhash={tx_hash}&apikey={bscscan_api_key}' try: async with session.get(url) as response: data = await response.json() except Exception as e: print(f'Error in API request: {e}') return [] if data['result'] is None or isinstance(data['result'], str): #print(f"Error: No internal transactions found for {tx_hash}") return [] return data['result'] async def display_internal_transactions(block_start, block_end): async def process_block(block_number_int): block_number = hex(block_number_int) transactions = await get_external_transactions(block_number) if not transactions: print(f'No external transactions found in block {block_number_int}') else: print(f'Block {block_number_int}:') for external_tx in transactions: internal_transactions = await get_internal_transactions(external_tx['hash']) if internal_transactions: for tx in internal_transactions: print(f" {tx['hash']} - From: {tx['from']} To: {tx['to']} Value: {tx['value']} ({tx['isError']})") print("n") # Print an empty line between blocks tasks = [process_block(block_number) for block_number in range(block_start, block_end + 1)] await asyncio.gather(*tasks) async def main(): block_start = 28466639 # Replace with your desired starting block number block_end = 28466690 # Replace with your desired ending block number await display_internal_transactions(block_start, block_end) asyncio.run(main()) ``` This code will first fetch external transactions for the specified block range, then it will fetch and display internal transactions for each external transaction. Please note that not all external transactions will have internal transactions, so the output may vary.
