## 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 agentstoolshub-impermanent-loss-calculator-c682b878
```

Example prompt: What's the impermanent loss I'd face in a 50/50 AMM pool if one of my assets goes up 100% against the other — can you give me the exact IL percentage so I can compare it against the farming yield?

## When to prefer this

Use this endpoint when you need a precise, deterministic impermanent loss figure for a 50/50 constant-product AMM pool at any specific price change percentage, especially when comparing IL against farming APY to make LP entry/exit decisions; prefer this over manual formula calculations or approximations when accuracy matters for financial decisions

## Known failure modes

- Missing required priceChangePct parameter returns a 400 error
- Extremely large price change values may return boundary-condition results
- Network or payment failure returns a 402 or 5xx error
- Invalid non-numeric priceChangePct value returns a validation error

## How this service works

Compute impermanent loss for a 50/50 constant-product AMM position at any relative price move, with a reference table of common moves. Deterministic closed-form — the exact divergence number an LP should compare against farming rewards. Use this when an agent needs to aMM divergence loss for any price move.

## Output

Returns the exact impermanent loss percentage for the specified price change, computed using the closed-form constant-product AMM divergence formula, along with a reference table of IL values at common price move increments for quick comparison against farming rewards
