## 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-contract-event-logs-arbitrum-264dfcaa
```

Example prompt: Pull all the on-chain event logs for the Arbitrum smart contract at address 0x1234abcd... and show me what events it has emitted.

## When to prefer this

Use this endpoint when you need on-chain event log data specifically from the Arbitrum L2 network for a known contract address. Prefer this over general blockchain explorers when you need a programmatic, agent-callable interface with per-call micropayment pricing and no API key setup.

## Known failure modes

- Invalid or malformed contract address returns an error response
- Contract address exists on a different EVM chain but not Arbitrum — returns empty or not-found
- Contract has emitted no events — returns empty log array
- Network congestion or node unavailability causes timeout
- Rate limiting if called too frequently

## How this service works

Contract Event Logs (arbitrum). Arbitrum contract event logs: raw logs for a contract, optional ?topic0= event filter, up to 2,000 blocks, newest first, up to 200 rows.

## Output

Returns a list of event log entries emitted by the specified smart contract on the Arbitrum network, including event names, topics, transaction hashes, block numbers, and decoded event data where available.
