## 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 qorevia-strategy-grade-09611a5b -d '<json body>'
```

Example prompt: Can you grade my trading strategy? It has 320 trades, a 58% win rate, profit factor of 1.85, max drawdown of 12%, and a 75% walk-forward pass rate — I want to see the composite score and component breakdown.

## When to prefer this

Use this endpoint when you need a structured, multi-dimensional quality score for a trading strategy based on standard backtest metrics. It is purpose-built for algorithmic trading evaluation, combining walk-forward robustness and drawdown into a single composite grade — making it more useful than manual metric inspection or generic statistics APIs.

## Known failure modes

- Missing or non-numeric input fields may return a validation error
- Extreme or out-of-range values (e.g. negative profit factor) may produce unreliable scores
- Network or payment authorization failure returns 402 if USDC payment is not settled
- Empty or zero-trade input may result in a degenerate or zero score

## How this service works

Agent-payable market intelligence and finance tools.

## Output

Returns a composite strategy score (e.g. 72.8 out of 100) plus individual component scores for profit factor, sample size, drawdown, and walk-forward performance — all as numeric values in a JSON object.
