How this service works
Non-custodial swap calldata for Base: give tokenIn, tokenOut, raw amountIn, slippage and recipient; we read Aerodrome and Uniswap V3 on-chain state, pick the max-output route, and return ready-to-sign transaction calldata plus the ERC-20 approval, amountOutMin, price impact and the venues compared. You sign with your own wallet — we never hold or move funds.
Output
Returns ready-to-sign EVM transaction calldata for the optimal swap route, the required ERC-20 approval payload, the minimum output amount (amountOutMin), estimated price impact percentage, and a breakdown of the venues (Aerodrome, Uniswap V3) that were compared with their respective output quotes.
Example use cases
DeFi bot executing optimal Base swaps
“I want to swap 500 USDC (500000000 raw units) for AERO on Base, sending tokens to 0xDeF456...789 — find me the best route between Aerodrome and Uniswap V3, use 100 bps slippage, and give me the calldata I can sign immediately.”
Pre-trade price impact check
“Before I commit to swapping 2 WETH (2000000000000000000 raw units) for USDC on Base to address 0x1234...abcd, can you quote the best DEX route and tell me the expected price impact and minimum amount I'd receive?”
Yield strategy token rebalancing
“I need to rebalance my Base portfolio — quote me a swap from AERO to WETH, selling 10000 AERO (that's 10000000000000000000000 raw units), recipient 0xFeed...cafe, 75 bps slippage, and show me whether Aerodrome or Uniswap V3 gives a better deal.”
Technical details
Endpoint
GEThttps://api.agentstools.dev/swap/quote?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need non-custodial DEX swap calldata specifically on Base mainnet, want automatic route comparison between Aerodrome and Uniswap V3, and need the full transaction ready to sign with your own wallet — without giving any third party custody of funds. Prefer this over generic swap APIs when you need Base-native DEX routing, price impact visibility, and built-in ERC-20 approval generation in a single call.
Side effects
- Unsupported token symbol or invalid ERC-20 address returns an error — use a supported symbol or a valid 0x Base address
- amountIn must be a non-zero integer string in raw atomic units; human-readable decimals will fail
- Recipient must be a valid 0x Ethereum address
- slippageBps exceeding 5000 is rejected
- Insufficient on-chain liquidity for the token pair may return no viable route
- Network or RPC issues reading Aerodrome or Uniswap V3 on-chain state may cause transient failures
