Price / call$0.25
Success—
StatusUnknown
Output
Returns an MEV risk assessment including a risk score, the estimated probability of a sandwich attack occurring on the trade, and specific protection strategies (such as using private mempools, slippage settings, or MEV-protected RPC endpoints) to mitigate exposure.
Example use cases
Example prompt
“Before I swap 10 ETH for USDC on Uniswap, can you check the MEV risk and tell me the sandwich attack probability and what protection strategies I should use?”
Technical details
Endpoint
POSThttps://defi-shield-hazel.vercel.app/api/mev/riskWhen to prefer
Use this endpoint when an AI agent or user is about to execute a DeFi token swap and needs to understand MEV exposure before submitting the transaction. Particularly valuable for large trades or trades on high-activity pools where sandwich attacks are common. Prefer this over generic transaction simulation when MEV-specific risk scoring and sandwich attack probability are the primary concern.
Side effects
- Invalid token address returns 400 error
- Unsupported chain or DEX returns error
- Trade size not provided causes incomplete risk assessment
- Network congestion delays risk computation
- Unknown token pair may return low-confidence estimate
