## How to call it through Zero

```sh
zero fetch --capability x402stock-sma-indicator-2c489103
```

## When to prefer this

Choose this endpoint when you need a ready-computed SMA time series without building your own OHLCV pipeline — ideal for technical analysis tasks where you need moving average values quickly, pay per call with no API key, and want configurable window/timespan/series_type tuning. Prefer this over raw OHLCV endpoints when the downstream task only needs smoothed price signals rather than raw candles.

## Known failure modes

- Invalid or unsupported ticker symbol returns an error or empty result
- Window or limit value outside allowed range (0 < window ≤ 2000, 0 < limit ≤ 5000) returns a validation error
- Unsupported timespan or series_type enum value returns a 400 error
- Payment not fulfilled via x402/USDC results in a 402 Payment Required response
- Insufficient historical data for the requested window/timespan combination may return fewer points than expected

## How this service works

Simple Moving Average time series. Tune with `?window=`, `?timespan=`, `?series_type=`, `?limit=`. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.

## Output

An array of timestamped SMA data points for the requested ticker, computed over the specified window and timespan on the chosen price series (open, high, low, or close). Each entry contains a timestamp and the SMA value for that period.
