## 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 rsi-indicator-47b10838
```

Example prompt: Can you get me the 14-day RSI for AAPL on a daily timespan for the last 30 data points, using close prices?

## When to prefer this

Use this endpoint when you need RSI-specific momentum indicator data for equities and want flexible configuration of window size, timespan granularity, and price series type. Prefer this over SMA or EMA endpoints when the user specifically needs overbought/oversold signals rather than trend-following averages.

## Known failure modes

- Invalid or unknown ticker symbol returns an error or empty result
- Case-sensitive ticker mismatch causes no data to be returned
- Timestamp range outside available data returns empty results
- Exceeding the maximum limit of 5000 causes a validation error
- Requesting RSI for a non-trading period (e.g., weekend with day timespan) may return no data

## How this service works

Get the relative strength index (RSI) for a ticker symbol over a given time range. Can't find what you're looking for? POST feedback to /feedback, no charge.

## Output

Returns a time-series array of RSI values for the specified ticker, each with a timestamp and computed RSI value. Configurable by window size, timespan, series type, date range, and sort order. Results are split-adjusted by default.
