## 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-il-calculator-0614ec0f -d '<json body>'
```

Example prompt: What would my impermanent loss be if one of my liquidity pool tokens goes up 75% in price? Give me the full breakdown with scenarios and interpretation.

## When to prefer this

Use this endpoint when an agent needs to quantify the impermanent loss risk for an AMM/liquidity pool position given a specific projected price change. Ideal for DeFi portfolio risk assessment, LP strategy evaluation, and educating users about IL before they deposit into a pool.

## Known failure modes

- Missing required field price_change_pct returns validation error
- Non-numeric price_change_pct causes schema error
- Payment failure via x402 USDC on Base returns 402 status
- Extreme or out-of-range price change values may produce edge-case outputs
- Service downtime on Vercel hosting returns 5xx

## 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, multiple price-change scenarios, the mathematical formula used, and a plain-English interpretation of the loss magnitude — all computed for the given price change input.
