## 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 speraxos-il-calculator-track-position-impermanent-loss-cc59b219 -d '<json body>'
```

Example prompt: What's my current impermanent loss on my Uniswap V3 position (NFT ID 845321) on Ethereum? My wallet is 0xAbC123...

## When to prefer this

Choose this endpoint when you need to quantify impermanent loss for a specific on-chain LP position on supported protocols (Uniswap V3, Curve, Balancer) across chains like Ethereum and Arbitrum. It is pay-per-call via x402 with no API key required, making it ideal for agentic workflows that need on-demand IL tracking without subscription overhead.

## Known failure modes

- Invalid or unsupported chain name returns error
- Unrecognized protocol name returns error
- Position ID not found on-chain returns not found error
- Pool address does not match wallet's position returns empty or error
- Payment of 0.005 USDC via x402 fails, request is rejected with 402 status
- Network RPC errors or on-chain data unavailability cause timeouts

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns the computed impermanent loss for the specified liquidity position, including IL percentage, dollar value lost relative to a hold strategy, current token composition, and position value metrics.
