Example use cases
DeFi protocol event audit
“Get me all the event logs for the Optimism contract at 0x7F5c764cBc14f9669B88837ca1490cCa17c31607 — I need to audit every event it has emitted on-chain.”

“Fetch the on-chain event logs for the NFT contract at 0x4200000000000000000000000000000000000006 on Optimism so I can see all Transfer and Mint events that have occurred.”
Smart contract debugging
“Can you retrieve the event logs for my deployed Optimism contract at 0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45? I'm trying to debug why certain events aren't firing as expected.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/optimism/events/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to retrieve historical or recent on-chain event logs for a specific EVM smart contract deployed on the Optimism L2 network. Prefer this over generic blockchain explorers when you need programmatic, agent-accessible access to contract events without manual UI interaction.
Side effects
- Invalid or malformed contract address returns an error
- Contract address with no emitted events returns an empty log list
- Network timeout or RPC node issues may cause delayed or failed responses
- Non-existent or undeployed contract address returns no results
- Rate limiting if too many requests are made in quick succession
