## 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-account-abstraction-operation-summary-1c480530
```

Example prompt: Can you pull up a summary of the account abstraction user operation with hash 0xabc123...def on the Ethereum mainnet chain — I want to understand what it did?

## When to prefer this

Choose this endpoint when you need a structured, human-readable summary of a specific ERC-4337 account abstraction user operation by its hash on a particular chain. It is ideal for debugging smart wallet transactions, auditing paymaster activity, or explaining gasless operations to users. Prefer this over general transaction lookup endpoints when the operation was submitted via a bundler and follows the ERC-4337 standard rather than a standard EOA transaction.

## Known failure modes

- Invalid or malformed operation hash returns an error or empty response
- Unsupported chain_id results in a 404 or chain-not-found error
- Operation hash not yet indexed returns empty or not-found response
- Network timeout if the Blockscout node for the given chain is slow to respond
- Incorrect chain_id for the operation yields no results even if hash is valid
