## 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-ethereum-contract-event-logs-45a299d3
```

Example prompt: Pull all the on-chain event logs for the Ethereum smart contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 so I can see what events it has emitted.

## When to prefer this

Choose this endpoint when you need raw on-chain event logs for a specific Ethereum contract address and want a simple REST call rather than running your own Ethereum node or using a heavier SDK. It is well-suited for agents that need to audit contract history, track token transfers, or monitor DeFi activity without managing RPC infrastructure. Prefer this over general blockchain explorers when programmatic, pay-per-call access is needed within an agentic workflow.

## Known failure modes

- Invalid or malformed Ethereum address returns an error
- Contract address with no events returns an empty log list
- Rate limiting or quota exceeded returns a payment/auth error
- Node connectivity issues may cause intermittent failures or timeouts
- Very high-activity contracts may return paginated or truncated results

## How this service works

Contract Event Logs (ethereum). Ethereum 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 Ethereum contract, including event topics, encoded data payloads, transaction hashes, block numbers, and log indices that allow downstream decoding of contract activity.
