## 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 simple-moving-average-sma-technical-indicator-c3524300
```

Example prompt: What's the 50-day simple moving average for AAPL using the daily close price — give me the last 30 data points in descending order.

## When to prefer this

Use this endpoint when you need trend-smoothing analysis via SMA for any supported asset class (stocks, crypto, forex, options). Prefer this over raw OHLC endpoints when you want pre-computed moving averages rather than raw candlestick data. Choose this over RSI when the user needs trend direction rather than momentum/overbought-oversold signals.

## Known failure modes

- Missing required 'ticker' parameter returns 400 validation error
- Invalid ticker symbol returns empty results or 404
- Window size outside valid range causes parameter error
- Payment not provided or insufficient USDC balance returns 402 Payment Required
- Timespan value not in allowed enum causes rejection
- Limit value outside 1-5000 range causes validation error
