How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with the computed output token amount (amount_out) based on the CPMM lite approximation of the V3 AMM formula, along with a schema identifier and a note clarifying the approximation method used (cpmm_lite_not_full_v3).
Example use cases
Pre-trade swap output estimation
“Before I execute a swap, can you tell me how much USDC I'd get out if I put in 500 units of ETH, given the pool has 80000 ETH in reserve and 160000 USDC in reserve?”
Slippage impact analysis for large trade
“I'm thinking of trading 5000 units into a pool with 50000 input reserve and 50000 output reserve — can you compute the output amount so I can see how much slippage I'm taking?”
Arbitrage opportunity sizing
“There's a V3 pool with 12000 input tokens and 9500 output tokens in reserve. If I put in 300 input tokens, what's my expected output so I can check if this arbitrage is profitable?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/amm-v3-amount-in-range?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap, pay-per-call computation of AMM swap output amounts without setting up any infrastructure or accounts. It is ideal for AI agents performing pre-trade simulation, arbitrage sizing, or slippage estimation on V3-style liquidity pools. Note that it uses a CPMM lite approximation, not the full Uniswap V3 concentrated liquidity math, so prefer it for quick estimates rather than precision-critical execution decisions.
Side effects
- Missing required fields (amount_in, reserve_in, reserve_out) result in an error response
- Zero or negative reserve values may cause division errors or undefined results
- Very large or very small amounts may lose precision due to floating point arithmetic
- Payment failure via x402 protocol results in 402 response and no computation
