AMM V3 Amount In Range Lite
x402
AMM V3 Amount In Range Lite is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Estimates the output amount for a concentrated liquidity (V3) AMM swap using constant-product math, assuming price stays within a specified range, without any on-chain calls.

How this service works
Lite constant-product amount when price stays in a range. Call when estimating concentrated LP swaps without on-chain state. Returns amount_out approx and note as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a deterministic JSON object containing amount_out (the approximate output token quantity for the swap) and a note clarifying that the result is advisory only, computed purely from local constant-product math with no on-chain data.
Example use cases
Pre-trade slippage estimation for LP
“I'm about to swap 1000 USDC into ETH in a concentrated liquidity pool that has 500000 USDC in reserve and 250 ETH in reserve — can you estimate how much ETH I'd get back using offline V3 constant-product math?”
Backtesting concentrated LP strategy
“For my backtest, calculate the approximate swap output if I put in 200 units with a pool reserve_in of 80000 and reserve_out of 160000, assuming price doesn't leave the liquidity range.”
Comparing swap sizes for position sizing
“I'm sizing a trade and need to compare outcomes: estimate the amount_out for swapping 50, 100, and 250 tokens into a pool with 10000 reserve_in and 20000 reserve_out using your V3 in-range constant-product formula.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/amm-v3-amount-in-rangeWhen to prefer
Choose this endpoint when you need a fast, deterministic, offline estimate of V3 concentrated liquidity swap output and have no need for live on-chain state or RPC access. It is ideal for pre-trade sizing, backtesting, or advisory UI displays where exactness is not critical and latency or RPC cost matters. Prefer alternatives (live on-chain quoters) when the trade is large relative to pool liquidity, when precision is critical for execution, or when price is likely to breach the assumed range.
Side effects
- Missing required fields (amount_in, reserve_in, reserve_out) result in a validation error
- Zero or negative reserve values may produce undefined or infinite results
- If price actually moves out of range during the swap, the estimate will be inaccurate — the endpoint does not account for partial range fills
- Payment failure over x402 protocol results in no computation returned
