# Impermanent Loss Calculator (DeFi/Uniswap)

> 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 to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability impermanent-loss-calculator-defi-uniswap-d1b785c7
```

Example prompt: What's the impermanent loss percentage for a Uniswap V2 LP position where the price of one token has doubled relative to when I entered the pool?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
