Example prompt: Can you pull all the on-chain contract events for address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum using ChainRay?

## When to prefer this

Use this endpoint when you need to retrieve the event log history for a specific smart contract or wallet address on a particular blockchain network. It is ideal for DeFi monitoring, auditing contract interactions, tracking token transfers or approvals, and understanding historical on-chain activity for a given address. Prefer this over generic block explorers when you need structured, agent-consumable event data across 46+ chains via a single API.

## Known failure modes

- Invalid or malformed address returns a 400 error
- Unsupported or unrecognized chain identifier returns an error
- Address with no contract events returns an empty result set
- Payment failure or insufficient USDC balance returns a 402 error
- Rate limiting or quota exceeded returns a 429 error
- Network congestion on the target chain may cause stale or delayed data
