## 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 defi-oracle-impermanent-loss-calculator-b28955a9 -d '<json body>'
```

Example prompt: Calculate the impermanent loss I'd face if the token price increases by 75% from when I entered a liquidity pool — show me the formula, the loss percentage, and how to interpret it.

## When to prefer this

Choose this endpoint when you need a quick, on-demand computation of impermanent loss for a single price-change scenario with full formula transparency and scenario comparison, especially within an AI agent workflow that pays per-call via USDC on Base. Prefer it over manual calculations when you want interpreted natural-language output alongside the raw numbers.

## Known failure modes

- Missing required price_change_pct field returns a validation error
- Extreme price change values (e.g. >10000%) may return unexpected or edge-case results
- Payment failure via x402 USDC on Base results in 402 response blocking the computation
- Non-numeric price_change_pct input returns a type error

## How this service works

DeFi data for AI agents — yield rates, swap routes, IL calculator, liquidation risk, MEV scanner, TVL tracking. Powered by DeFiLlama + on-chain RPC data. Pay with USDC on Base via x402.

## Output

Returns the impermanent loss percentage (impermanent_loss_pct), the mathematical formula used, an array of multiple price-change scenarios for comparison, and a plain-English interpretation of the loss magnitude and its implications for liquidity providers.
