How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns the computed amount_out (tokens received after fees) and impact_bps (price impact expressed in basis points, e.g. 530 bps = 5.3% slippage), along with the schema identifier and the input amount for verification.
Example use cases
Pre-trade slippage check for DeFi bot
“Before my trading bot submits a swap of 200 tokens on a pool with 50000 reserve_in, 48000 reserve_out, and 30 bps fee, tell me the price impact in basis points so I can decide if it's too high.”
Liquidity depth analysis for a DEX pool
“I want to understand how liquid this pool is — calculate the price impact in bps if someone trades 1000 tokens in, given reserve_in of 80000, reserve_out of 75000, and a 25 bps fee.”
Optimal trade size optimizer
“Help me find the right trade size — what's the AMM price impact in basis points for swapping 500 tokens into a pool with 20000 reserve_in and 18000 reserve_out at a 30 bps fee?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/amm-price-impact-bps?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, verifiable, pay-per-use computation of AMM price impact without setting up your own on-chain simulation or running a full DEX SDK. Ideal for AI agents that need to pre-screen trades for excessive slippage before executing, or analyze pool liquidity depth on the fly. Prefer this over custom implementations when you want deterministic, formula-based results with no signup overhead and USDC micropayment billing via x402.
Side effects
- Missing required fields (amount_in, reserve_in, reserve_out, fee_bps) returns validation error
- Zero or negative reserve values may cause division-by-zero or undefined behavior
- Payment not provided or insufficient USDC results in 402 Payment Required response
- Extremely large input amounts relative to reserves may produce unrealistically high impact values
