Slippage API

Price impact and slippage for a specific trade size on Polygon PoS - what will my trade actually get, not just the spot price. Simulates the swap against live reserves across QuickSwap, SushiSwap and Uniswap v3 and returns the best execution venue, amount out, price impact in bps, the pool fee separately, and what correct routing saves versus picking the best quoted price. Pre-trade execution check for trading bots and DEX aggregators on Polygon / MATIC / POL.
