## How to call it through Zero

```sh
zero fetch --capability ozmium-trading-scorecard-api-028ad2db
```

Example prompt: Pull up the full trading scorecard for Base address 0xAbC...123 — I want to see my win rate, profit factor, and R-multiple expectancy from all my closed leverage positions.

## When to prefer this

Use this endpoint when you need a comprehensive, aggregated trading performance scorecard for a specific Base wallet address derived from its closed leverage history. Ideal for risk-sizing agents, portfolio reviews, or self-assessment of trading edge. Prefer this over raw transaction queries when you need computed metrics like profit factor or R-multiple expectancy without doing the math yourself.

## Known failure modes

- Invalid or malformed Base address returns a 400 error
- Address with no closed leverage history returns zeroed or empty stats
- Payment not included or insufficient USDC results in 402 Payment Required
- Address on a non-Base network may return no data or an error
- Network congestion or chain data lag may cause stale or incomplete stats

## How this service works

Aggregate trading scorecard for any Base address from its closed leverage history: trades, wins/losses, win rate, net USD, gross profit / loss, profit factor, mean R-multiple expectancy, avg win / loss, best / worst trade. GET /v1/stats/{address}. The "am I actually good" read- and the input to a risk-sizing agent.

## Output

A JSON object containing the wallet address, total trade count, wins and losses, win rate (0–1), net USD PnL, gross profit, gross loss, profit factor, mean R-multiple expectancy, average win size, average loss size, best trade, and worst trade — all derived from the address's closed leverage position history on Base.
