Maps to POST /quote. Returns the best swap quote across all integrated DEX protocols, with router, callData, value, price impact, route summary, and gas estimate in one response. Surplus and positive slippage are returned to the user in the same transaction. Supports an optional affiliateCode (registered affiliate wallet address) forwarded to the API so the affiliate fee is paid on-chain to that address. Supports an excludePositions parameter that prices the swap excluding the caller's own LP position from pool state. Returns signable data only; never signs or broadcasts. EXECUTION FLOW: (1) If the input token is non-native, send an ERC-20 approve to the router and WAIT for on-chain confirmation. (2) Call this tool again for a fresh quote (quotes expire). (3) Send the tx to the router contract: to=router, data=callData, value=value. This requires a private key or wallet signer. ⚠️ PRICE IMPACT: The response includes a priceImpact field. Agents MUST present this value to the user and request explicit confirmation before executing. High price impact means the user will receive significantly less value than expected. ⚠️ ZERO OUTPUT: If the swap amount is too small relative to the token pair price ratio, the API returns HTTP 400 with "swap amount too small: output rounds to zero for this pair". Increase the amount or use a different pair.
