## How to call it through Zero

```sh
zero fetch --capability blockscout-address-logs-csv-export-000eaaf8
```

Example prompt: Can you download the event logs for address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum (chain ID 1) as a CSV from Blockscout, filtered from January 1 2024 to June 30 2024?

## When to prefer this

Use this endpoint when you need bulk, exportable event log data for a specific address on a specific blockchain in CSV format — ideal for auditing, tax reporting, compliance, or feeding on-chain data into spreadsheet or data analysis tools. Prefer this over JSON API alternatives when downstream workflows require CSV ingestion. Choose this over generic blockchain explorers when you need multichain support and structured export.

## Known failure modes

- Invalid chain_id returns 404 or empty response
- Invalid or malformed address_hash_param returns 400 error
- No logs found for the address in the given period returns empty CSV
- Unsupported chain_id for Blockscout returns error
- Invalid date format for from_period or to_period causes 400
- Rate limiting or payment failure returns 402 or 429
