Technical details
Endpoint
POSThttps://gpt55.558686.xyz/slippage-sentinel/entrypoints/estimate_slippage/invokeWhen to prefer
Use this endpoint when you need pre-trade risk analysis for DeFi swaps, specifically slippage and price impact estimates with route-risk warnings, before committing to an on-chain transaction. Prefer this over general MEV checkers when the primary concern is slippage tolerance and price impact rather than sandwich attack probability.
