An executable swap on Base, routed by 0x across Uniswap, Aerodrome, Balancer, Curve and more. Returns the transaction for your own wallet to sign, plus the approval step if needed, minimum out, route and fees. We never hold funds. Name tokens as ETH, USDC, WETH, cbBTC, AERO… or a 0x address; buying an unknown token runs a sellability check first and refuses a honeypot unless force=1.Overview
