## 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 technical-indicator-data-api-rsi-macd-sma-ema-9db20643 -d '<json body>'
```

Example prompt: Can you fetch the daily RSI values for AAPL using this technical indicator endpoint? I want to see the time-series data so I can check if it's currently overbought or oversold.

## When to prefer this

Choose this endpoint when you need computed technical indicator values (RSI, MACD, SMA, EMA, etc.) for a stock or crypto symbol as a time series, especially within an x402 pay-per-call workflow where you want a single unified API without managing multiple data provider subscriptions.

## Known failure modes

- Unknown or unsupported symbol returns empty data array
- Unsupported indicator string causes error or null response
- Invalid interval value may return error or default behavior
- Payment failure via x402 protocol blocks request
- Rate limiting or quota exhaustion returns 402 or 429 error
