How this service works
Lightweight swap quote for Base without calldata: give tokenIn, tokenOut and raw amountIn and get the max-output route across Aerodrome and Uniswap V3, the buy amount, amountOutMin, price impact and the venues compared. A cheap price check before you build the full transaction.
Output
Returns the optimal DEX route across Aerodrome and Uniswap V3, the expected buy amount in raw units, the minimum output amount (amountOutMin) after slippage, price impact percentage, and a breakdown of the venues compared — all without building a calldata transaction.
Example use cases
Example prompt
“Before I execute the transaction, check the best swap price for selling 1 WETH (1000000000000000000 raw units) to get USDC on Base — show me the best route across Aerodrome and Uniswap V3, the expected output, and price impact with 50 bps slippage.”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/swap/price?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap price check before constructing a full swap transaction on Base — especially when you want to compare Aerodrome and Uniswap V3 routes and assess price impact without the overhead of calldata generation. Prefer this over full swap-transaction endpoints when only a quote is needed for display, comparison, or pre-flight validation.
Side effects
- Unsupported token symbol or unrecognized ERC-20 address returns an error
- amountIn of zero or non-integer string causes validation failure
- slippageBps exceeding 5000 is rejected
- Token pair with no liquidity on either venue returns no route found
- Network issues or RPC timeouts cause transient 5xx errors
