Price / call$0.5
Success—
StatusUnknown

Example prompt
“Find me the optimal trading route to swap 5 ETH for USDC across DEXs — I want to minimize price impact and protect against MEV sandwich attacks as much as possible.”
Technical details
Endpoint
POSThttps://defi-shield-hazel.vercel.app/api/mev/optimal-routeWhen to prefer
Use this endpoint when an AI agent or user needs to execute a DeFi token swap and wants to minimize both price impact from large trades and MEV exposure (front-running, sandwich attacks). Particularly valuable for trades above a few hundred dollars where routing quality meaningfully affects execution price. Prefer over generic DEX aggregators when MEV protection is an explicit concern.
Side effects
- Invalid or unsupported token address — endpoint returns error indicating unrecognized token
- Trade size too large for available liquidity — returns warning about insufficient pool depth
- Network congestion causing stale route data — may return outdated pricing information
- Unsupported token pair with no viable DEX path — returns no-route-found error
- Payment of 0.5 USDC not processed — returns 402 payment required
