## 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 otto-ai-technical-signals-4286ad5d
```

Example prompt: What are the technical signals for AAPL right now — RSI, moving averages, trend state, and recent momentum?

## When to prefer this

Choose this endpoint when you need quantitative technical indicators — RSI, SMAs, trend state, and momentum — for US equities or ETFs, especially for pre-trade screening, trend confirmation, or overbought/oversold detection. It is backed by Tiingo adjusted-close data, making it reliable for momentum and moving average accuracy. Prefer it over crypto-focused signals endpoints when the asset is a traditional equity or ETF ticker.

## Known failure modes

- Unsupported ticker symbol returns an error or empty data payload
- Stale data if market is closed or provider is degraded (meta.degraded=true)
- Missing queryParams.ticker parameter causes a 400-level error
- Network or payment authentication failure returns a 402 or 5xx

## How this service works

Daily technical snapshot for a vendor-resolved equity from licensed Tiingo adjusted closes: Wilder RSI-14, 20-session momentum, SMA-20/SMA-50, price distance from each average, above/below/mixed trend state, and the latest observed golden/death cross. Price and averages retain Tiingo payload units because the captured feed does not identify a currency.

## Output

A JSON object containing the ticker's RSI-14, adjusted close price, SMA-20, SMA-50, trend state (e.g. 'above-both'), 20-session momentum percentage, the data provider (Tiingo), and metadata including generation timestamp and staleness in seconds. Status field confirms success.
