## 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 api-quantoracle-dev-9185cd76 -d '<json body>'
```

Example prompt: Backtest a simple 50/200-day moving average crossover strategy on BTC/USD using daily data from January 2020 through December 2023, and give me the total return, max drawdown, and Sharpe ratio.

## When to prefer this

Choose this endpoint when you need to evaluate the historical performance of a defined algorithmic trading strategy before deploying it live. It is best suited for quantitative traders and AI agents that need to validate strategy viability, measure risk-adjusted returns, or compare strategy variants using backtesting — rather than live signal generation or portfolio management.

## Known failure modes

- Invalid strategy definition or unsupported strategy type returns 400 error
- Asset symbol not found or unsupported in historical database returns 404
- Date range out of bounds or insufficient historical data returns 422
- Malformed request body missing required strategy parameters returns 400
- Service timeout for very large date ranges or complex strategies
- Payment not processed or insufficient balance returns 402
