How this service works
Read contract event logs across a strictly bounded block range with an optional topic0 filter and capped response count.
Output
Returns a JSON object containing an array of raw EVM event log entries, each with a transaction hash, array of topics, and hex-encoded data field, plus metadata: the network name, total log count returned, a success flag, and a truncated flag indicating whether the result set was capped at the requested limit.
Example use cases
Monitor DeFi protocol events on Base
“Fetch the last 100 event logs for the Uniswap V3 pool contract 0x4e68Ccd3E89f51C3074ca5072bbAC773960dFa36 on Base, from block 12000000 to the latest block.”
Audit ERC-20 Transfer activity
“Get up to 500 Transfer event logs for the USDC contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum between blocks 19500000 and 19502000, filtered by topic 0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef.”
Investigate smart contract activity on Arbitrum
“Retrieve event logs for the contract 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 on Arbitrum from block 150000000 to block 150002000, limit to 50 results.”
Technical details
Endpoint
GEThttps://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/evm_logsWhen to prefer
Choose this endpoint when you need raw on-chain event logs for a specific contract address on Base, Ethereum, or Arbitrum, especially when you want to filter by event signature (topic0) and control the block range precisely. It is pay-per-use at $0.003 USDC via x402, making it suitable for sporadic or agent-driven queries without a subscription. Prefer alternatives (e.g. a full indexer or TheGraph) if you need decoded, human-readable events, historical data beyond 2,000-block windows at scale, or multi-contract queries in one call.
Side effects
- Missing required contract address parameter returns validation error
- Block range exceeds 2,000 blocks returns an error or truncated result
- Invalid chain name (not base/ethereum/arbitrum) returns an error
- Contract address not found on specified chain returns empty logs array
- topic0 hash format invalid returns a parsing error
- Payment not settled via x402 returns HTTP 402
