## How to call it through Zero

```sh
zero fetch --capability chainray-online-97c62ac9
```

Example prompt: What's my impermanent loss on Base if I entered my LP position at $1800 and the token is now at $2700?

## When to prefer this

Use this endpoint when an agent needs to compute impermanent loss for a DeFi liquidity provider position on Base or other supported chains, especially when on-chain proof of the calculation is desired. Prefer this over manual calculation when you need simulation scenarios across multiple price points in a single call.

## Known failure modes

- Missing entryPrice or currentPrice query params returns a tip message with example usage rather than an error
- Invalid or non-numeric price values may produce unexpected results
- Chain parameter mismatch — service defaults to Base regardless of requested chain
- Network timeout or service unavailability returns HTTP error
- Negative or zero prices may cause formula errors

## How this service works

Computes impermanent loss for liquidity providers using entry and current token prices on a specified chain (supports Base).

## Output

Returns impermanent loss as a percentage, dollar loss per $10,000 invested, the IL formula used (2√(p1/p0)/(1+p1/p0)-1), multiple simulation scenarios across price ranges, an on-chain cryptographic proof anchored to a Base block, and the current timestamp.
