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.
Example use cases
Uniswap v3 out-of-range IL check
“My Uniswap v3 position was opened at a price of 2000, with a concentrated range between 1800 and 2400. The price has moved to 2600 — calculate my impermanent loss, flag whether I'm out of range, and tell me what my token composition looks like now.”
Uniswap v2 full-range IL estimate
“I provided full-range liquidity on Uniswap v2 when ETH was at 1500 USDC. It's now at 2500 USDC. How much impermanent loss have I suffered compared to just holding, and what's my current token split?”
Pre-entry IL scenario planning
“Before I add liquidity to a Uniswap v3 pool, I want to know: if the entry price is 100 and I set a range of 80 to 130, what would my impermanent loss be if the price drops to 75? Would I be out of range at that point?”
Technical details
Endpoint
POSThttps://api.vextorium.com/calculadora-il-pago?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
