## 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 x402-gateway-production-up-railway-app-faff7440 -d '<json body>'
```

Example prompt: What are my realized and unrealized profits and losses broken down by token for wallet address 0x1234abcd...?

## When to prefer this

Use this endpoint when you need per-token realized and unrealized profit/loss analytics for a specific crypto wallet, especially in DeFi portfolio tracking, tax reporting prep, or trading performance review contexts. Prefer this over general balance endpoints when the user needs gain/loss figures rather than raw holdings.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Wallet with no transaction history may return empty or zero PnL
- Unsupported chain or token may be omitted from results
- Network timeouts if on-chain data indexing is slow
- Rate limiting or payment failure if USDC balance insufficient

## How this service works

Realized and unrealized profit & loss per token for any wallet

## Output

A breakdown of realized and unrealized PnL per token held or traded by the specified wallet, showing how much profit or loss has been locked in versus what remains on paper.
