## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability blockscout-address-internal-transactions-csv-export-88852883
```

Example prompt: Can you export all internal transactions for Ethereum address 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B on chain ID 1 as a CSV, filtered from January 1 2024 to June 30 2024?

## When to prefer this

Use this endpoint when you need bulk internal transaction data for a specific address in CSV format for offline analysis, accounting, or tax reporting. Prefer this over paginated JSON endpoints when you need complete historical data across a date range. Ideal for auditing smart contract internal calls or generating financial reports across any Blockscout-supported EVM chain.

## Known failure modes

- Invalid chain_id returns 404 or empty response
- Invalid address_hash_param returns 400 bad request
- No transactions in the specified date range returns empty CSV
- Malformed date filter values may return 422 unprocessable entity
- Rate limiting or payment failure returns 402 or 429
- Very large address histories may time out
