## 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-by-massive-34624f60
```

Example prompt: Can you get me the 50-day simple moving average for AAPL using daily close prices, returning the last 30 data points in descending order?

## When to prefer this

Use this endpoint when you need smoothed price trend data for a stock using the classic simple moving average calculation. Prefer this over raw OHLC data when you want noise-reduced trend signals. Choose SMA over EMA (also available on this platform) when you want equal weighting across all periods in the window rather than recency-biased weighting. Ideal for technical analysis agents, charting workflows, or momentum detection pipelines.

## Known failure modes

- Invalid or unsupported ticker symbol returns an error or empty result
- Requesting data before a ticker's listing date returns no results
- Window size larger than available data may return sparse or no values
- Invalid timestamp format causes a query error
- Exceeding the maximum limit of 5000 returns a validation error
- Network or provider outage returns a 5xx error

## Output

Returns a time-ordered list of SMA data points, each containing the calculated SMA value and corresponding timestamp. Includes metadata such as the window size, timespan, and series type used. Supports pagination via limit and order parameters.
