Technical details
Endpoint
POSThttps://defi-shield-hazel.vercel.app/api/mev/mempool-scanWhen to prefer
Use this endpoint when you need real-time detection of MEV activity and large pending trades for a specific DeFi token before executing a swap or analyzing market conditions. Prefer this over generic blockchain explorers when you specifically need mempool-level (pre-confirmation) data and MEV pattern recognition rather than confirmed transaction history.
Side effects
- Invalid or unrecognized token address returns error
- Token has no recent mempool activity, resulting in empty results
- Mempool data provider unavailable or rate-limited
- Network congestion causing stale or incomplete mempool snapshot
- Unsupported chain or token standard
