## 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 market-intelligence-api-backtest-c75cdaf4
```

Example prompt: Run a backtest on my moving-average crossover strategy using the Market Intelligence API and show me the performance metrics — equity curve, Sharpe ratio, and total return.

## When to prefer this

Use this endpoint when you need to evaluate a trading strategy's historical performance before deploying it live, especially when you want quantitative metrics like Sharpe ratio, drawdown, and return curves. Prefer this over live market data endpoints when the goal is strategy validation rather than real-time signal generation.

## Known failure modes

- Missing required strategy parameters returns a 400 bad request error
- Invalid or unsupported strategy type causes a validation error
- Insufficient historical data for the requested period returns an error
- Payment not received (402) blocks execution
- Server-side computation timeout for complex strategies
