How this service works
Event logs for an address in a block range
Output
An array of event log entries for the specified address and block range, each containing the transaction hash, block number, log index, event topics (including the event signature hash), and raw log data — enabling reconstruction of on-chain activity and event decoding.
Example use cases
Track ERC-20 Transfer Events
“Get me all the Transfer event logs from the USDC contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 between blocks 19000000 and 19010000 so I can see recent transfer activity.”
Monitor DeFi Protocol Activity
“Fetch all event logs from the Uniswap V3 pool at 0x8ad599c3A0ff1De082011EFDDc58f1908eb6e6D8 for blocks 18900000 through 18950000 — I want to see all Swap and Mint events.”
Audit Smart Contract Events
“Pull every on-chain event log from contract 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D between block 18500000 and 18600000 so I can audit what happened during that period.”
Technical details
Endpoint
GEThttps://santyvv-x402.santyvv1993.workers.dev/api/chain/logs?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need raw event logs for a specific contract or address over a defined block range on EVM-compatible chains. Ideal for auditing smart contract activity, tracking token transfers, monitoring DeFi protocol events, or reconstructing historical on-chain state. Prefer this over full transaction history endpoints when you specifically need event/log data rather than transaction receipts or state reads.
Side effects
- Block range too large causing timeout or rate limit error
- Invalid or checksummed address format rejected
- Block range references future blocks not yet mined
- Unsupported chain ID returns empty or error response
- No logs found returns empty array (not an error)
- Missing required query parameters returns 400 bad request
