## When to prefer this

Use this endpoint when you specifically need to look up an Arbitrum data availability batch on EigenDA by its data hash via Blockscout's API. It is the right choice for verifying, auditing, or debugging EigenDA-backed Arbitrum batches. Prefer this over generic block explorers when you need structured JSON data about EigenDA DA batches programmatically.

## Known failure modes

- Invalid or unknown data_hash returns empty result or 404
- Invalid chain_id returns an error or no data
- Malformed hash format causes a bad request error
- EigenDA batch not yet indexed returns empty response
- Rate limiting or payment failure returns 402 or 429
