How this service works
67 paid endpoints for on-chain, forex, stocks & market intelligence
Output
Returns a list of structured on-chain event log objects including event name, emitting contract address, transaction hash, block number, log index, and decoded event parameters (topics and data) for each matched event.
Example use cases
DeFi protocol activity audit
“Get all Swap events from the Uniswap V3 ETH/USDC pool contract 0x8ad599c3A0ff1De082011EFDDc58f1908eb6e6D8 on Ethereum mainnet for the last 500 blocks so I can analyze recent trading activity.”
NFT mint tracking
“Fetch all Transfer events where the sender is the zero address from the NFT contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on chain ID 1 — I want to see all recent mints.”
Token approval monitoring
“Retrieve all Approval events emitted by the WETH contract 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 on Ethereum mainnet so I can audit which addresses have been granted spending allowances.”
Technical details
Endpoint
POSThttps://trading-hub-v4-omega.vercel.app/api/contract/events?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain smart contract event data from EVM-compatible blockchains, particularly for DeFi monitoring, NFT activity, token transfers, or any event-driven blockchain analytics. Prefer this over block explorers like Etherscan when you need machine-readable, structured event data via API for programmatic agent workflows. Best for scenarios requiring real-time or historical event retrieval without running your own node.
Side effects
- Invalid or non-existent contract address returns empty results or 400 error
- Unsupported chain ID returns an error
- Block range too large may time out or be rejected
- Contract has no ABI indexed — events may be undecoded
- Payment not attached or insufficient USDC balance returns 402
- Rate limiting if too many requests in rapid succession
