Example use cases
DEX swap event monitoring
“Watch the Uniswap V3 WETH/USDC contract on Ethereum for any Swap events and alert me immediately so my bot can execute its arbitrage strategy.”
Token transfer detection for bots

DeFi liquidation trigger tracking
“Monitor the Aave lending pool contract on Ethereum mainnet for LiquidationCall events and send me an alert each time one fires so I can track liquidation opportunities.”
Technical details
Endpoint
POSThttps://x402-chain-intel.vercel.app/api/alert/contract-events?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your trading bot or automated agent needs real-time or near-real-time alerts for specific smart contract events on-chain. It is well-suited for DeFi bots that react to swap, transfer, liquidation, or custom contract events as trading signals. Prefer it over generic blockchain explorers when you need a programmatic, paid, low-latency alert feed designed for automated consumption.
Side effects
- Invalid or unrecognized contract address returns an error
- Unsupported blockchain network returns 400 or 422
- Malformed event filter criteria cause rejected requests
- Payment not settled results in 402 response blocking the call
- No matching events found within the query window returns empty result set
