# Vextorium Impermanent Loss Calculator

> Vextorium Impermanent Loss Calculator is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).

Calculates impermanent loss for Uniswap v2 (full range) and v3/v4 (concentrated range) positions, including IL vs holding comparison, out-of-range flag, and final token composition.

## 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 vextorium-impermanent-loss-calculator-9b64718e -d '<json body>'
```

Example prompt: I entered a Uniswap v3 concentrated liquidity position when the price was 1800 USDC per ETH, with a range from 1600 to 2200. The current price is now 2500 — can you calculate my impermanent loss, tell me if I'm out of range, and show my final token mix?

## When to prefer this

Use this endpoint when you need a fast, structured computation of impermanent loss for Uniswap v2 or v3/v4 positions without querying on-chain data — ideal for pre-entry scenario planning, portfolio monitoring, or educational tools. Prefer this over on-chain pool queries (like the sibling Uniswap v3 pool state endpoint) when you already know the entry and current prices and just need the IL math.

## Known failure modes

- Missing required fields (precio_inicial or precio_final) returns a validation error
- Invalid numeric types for price inputs cause a 400 error
- Providing rango_min > rango_max may result in unexpected IL output or an error
- Extreme price ratios (e.g. 0 or near-infinity) may return null values for some fields
- If the pool type cannot be determined from inputs, tipo and nota may be null

## How this service works

Impermanent loss calculator for Uniswap v2 (full range) and v3/v4 concentrated ranges: IL vs holding, out-of-range flag and final token mix.

## Output

Returns an object with: impermanent loss as a percentage (perdida_impermanente_pct), price change percentage (cambio_precio_pct), whether the position is out of range (fuera_de_rango boolean), final token composition showing token0 and token1 percentages, the pool type (v2 full range or v3 concentrated), the price range used, and an optional note with additional context.
