How this service works

Exact answers for AI agents: 40+ tools for EVM chains and Aptos, gas on 14 chains, never a guess. Free tier; pay per call in USDC (x402) on 13 networks.

Output

A JSON response with ok:true and an array of EVM event log objects matching the specified address, topics, and block range — each log includes block number, transaction hash, log index, address, topics array, and raw data field.

Example use cases

Track DeFi protocol deposits

“Get me the Deposit event logs for the Aave V3 pool contract at 0x87870Bca3F3fD6335C3F4ce8392D69350B4fA4E2 on Ethereum (eip155:1) from block 19500000 to 19600000 — the Deposit topic is 0x804c9b842b2748a22bb64b345453a3de7ca54a6ca45ce00d415894979e22897a.”

Audit NFT mints on Base

“Fetch Transfer logs from the zero address for the NFT contract 0xd4307e0acd12cf46fd6cf93bc264f5d5d1598792 on Base (eip155:8453) from block 10000000 to 10050000, using topic 0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef.”

Monitor token swaps on Polygon

Technical details

Endpoint

POSThttps://logicnodes.io/paid/v1/tools/evm_logs?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need precise, deterministic on-chain event log retrieval for EVM-compatible chains and want pay-per-call USDC pricing without a subscription. It is ideal for AI agents that need exact blockchain data rather than approximations, support CAIP-2 chain identification, and operate across 13+ EVM networks including Base, Ethereum, and Polygon.

Side effects

Chain name provided instead of CAIP-2 or numeric chain ID — request refused
Address fails EIP-55 checksum validation when mixed-case — rejected
Topics array exceeds 4 items — validation error
fromBlock or toBlock out of range or malformed — error response
Chain ID not supported — unsupported chain error
Payment not provided or insufficient USDC — 402 Payment Required
