## 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-relative-strength-index-technical-indicator-25918ddf
```

Example prompt: What's the 14-period RSI for AAPL on daily close prices for the last 100 data points? I want to know if it's overbought or oversold.

## When to prefer this

Use this endpoint when you need RSI momentum analysis for any asset class (stocks, crypto, forex, options) with configurable window size and timespan. Prefer this over SMA endpoint when specifically evaluating overbought/oversold conditions rather than trend direction. Ideal for systematic technical analysis workflows and trading signal generation.

## Known failure modes

- Invalid or unsupported ticker symbol returns an error or empty result
- Window size outside acceptable range causes a bad request
- Payment of 0.015 USDC not fulfilled causes 402 Payment Required
- Rate limiting may return 429 Too Many Requests
- Invalid timespan string (e.g. typo) returns a validation error
- Requesting data for a ticker with insufficient historical data may return partial results
