Impermanent Loss Calculator (DeFi/Uniswap)
x402
Impermanent Loss Calculator (DeFi/Uniswap) is a paid API for AI agents from dominion-data.x402-evm-math.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-29).
Calculates the impermanent loss percentage for a liquidity position given price changes, supporting Uniswap V2/V3 math.

How this service works
Exact EVM address, calldata, Uniswap V2/V3 and impermanent-loss math. Pay per call in USDC on Base via x402.
Output
Returns a JSON object containing `impermanent_loss_pct`, a string representing the impermanent loss as a negative percentage (e.g. '-5.7191'), indicating how much value a liquidity provider has lost relative to simply holding the tokens outside the pool.
Example use cases
LP position risk check before entry
“If I provide liquidity to a Uniswap pool and one token triples in price relative to the other, what percentage of my value would I lose to impermanent loss compared to just holding?”
Post-trade IL damage assessment
“I had a Uniswap V2 liquidity position and the price ratio between my two tokens shifted by 80% since I entered — can you calculate my impermanent loss percentage so I can decide whether to exit?”
DeFi yield strategy breakeven analysis
“I'm earning 12% APY as a Uniswap LP but I'm worried about IL — calculate my impermanent loss if prices diverge by 40% so I can see if fees actually cover my losses.”
Technical details
Endpoint
GEThttps://dominion-data.x402-evm-math.workers.dev/defi/impermanent-loss?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a precise, pay-per-call computation of impermanent loss for Uniswap V2/V3 AMM positions without standing up your own math library. Ideal for DeFi agents that need on-demand IL calculations as part of broader liquidity strategy workflows, especially when paired with the sibling EVM calldata and Uniswap math endpoints on the same platform. At $0.001 USDC per call, it is cost-effective for frequent per-decision computations.
Side effects
- Missing required query parameters (price ratio inputs) returns an error or undefined result
- Invalid numeric input types may cause computation errors
- Extreme price ratios may yield edge-case results; no input validation is documented
- No documented error schema — failures may return non-standard responses
