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 impermanent loss as a percentage (il_pct, e.g. -2.02) and as a decimal fraction (il_fraction, e.g. -0.0202), along with a schema identifier string. Negative values indicate value lost relative to simply holding the tokens.
Example use cases
LP position risk assessment before entry
“If ETH price doubles relative to USDC after I deposit into a Uniswap v2 pool, what percentage of value will I lose to impermanent loss? The new-to-old price ratio would be 2.”
Post-hoc IL calculation after price move
“ETH dropped to 60% of its price when I entered my liquidity pool. Can you calculate exactly how much impermanent loss I incurred? The price ratio is 0.6.”
Compare IL across multiple price scenarios
“I want to understand my IL exposure — can you compute the impermanent loss fraction for a price ratio of 1.25, so I can decide whether staying in this LP is worth it?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/il-constant-product?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, formula-based computation of impermanent loss for a constant-product (x*y=k) AMM, such as Uniswap v2 or SushiSwap, given a known price ratio change. It is ideal for agents performing DeFi risk analysis, LP position tracking, or portfolio reporting without needing to integrate a full on-chain data provider. Pay-per-call USDC pricing via x402 means no API key management.
Side effects
- Missing price_ratio field returns a validation error
- Non-numeric price_ratio causes a bad request response
- price_ratio of 0 or negative may cause division errors or undefined math
- Payment not settled via x402 protocol results in 402 Payment Required response
