## 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 saylor-innovations-evm-transaction-details-optimism-67046348
```

Example prompt: Can you pull up the full on-chain details for Optimism transaction 0x4a7b3c2d1e9f8a6b5c4d3e2f1a0b9c8d7e6f5a4b3c2d1e9f8a6b5c4d3e2f1a0b — I need the sender, recipient, value transferred, gas used, and whether it succeeded.

## When to prefer this

Use this endpoint when you specifically need full transaction details on the Optimism (OP Mainnet) Layer 2 network. It is purpose-built for Optimism and will not return results for transactions on Ethereum mainnet, Base, or BSC — use sibling endpoints for those chains. Prefer this over generic block explorer scraping when you need structured, machine-readable transaction data suitable for programmatic processing by an AI agent.

## Known failure modes

- Transaction hash not found on Optimism — returns 404 or empty result if the hash doesn't exist on the network
- Invalid hash format — malformed or non-hex hash strings may return a 400 error
- Network connectivity issues — temporary failures reaching the Optimism RPC node
- Pending transactions — very recent transactions not yet confirmed may return incomplete data
- Wrong network — submitting an Ethereum or Base transaction hash will return no result since this endpoint is Optimism-specific

## How this service works

EVM Transaction Details (optimism). Optimism transaction details: status, from/to, value, block, nonce, gas used, total fee (incl. L1 data fee on OP-stack chains), event count and method selector.

## Output

Returns full transaction details for the specified Optimism transaction hash, including sender and recipient addresses, ETH value transferred, gas limit and gas used, transaction status (success/failure), block number and timestamp, input calldata, and event logs emitted during execution.
