## 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 saylor-innovations-data-desk-technical-indicators-8f3512fd
```

Example prompt: Can you run technical indicators — RSI, MACD, Bollinger Bands, SMA, and EMA — on these closing prices and tell me if the asset looks overbought or what the trend signal is: 44.5,45.1,46.3,45.8,47.2,48.0,47.5,49.1,50.0,51.2,52.0,51.8,53.0,54.1,55.0,54.5,56.2,57.0,56.8,58.1,59.3,60.0,59.5,61.0,62.1,63.0?

## When to prefer this

Choose this endpoint when you need multiple classic technical indicators computed simultaneously from raw closing prices without maintaining your own calculation library. It is especially useful for AI agents doing quick momentum or trend checks on crypto or stock price series, and when you want a plain-language interpretation alongside the numeric values rather than raw numbers alone.

## Known failure modes

- Fewer than 2 prices supplied — indicators will be null or missing
- Fewer than 26 prices — MACD returns null
- Non-numeric values in the price string cause parsing errors
- Too many prices (over 1000) may be rejected
- Malformed comma-separated string returns an error response
- Payment failure (x402) if USDC balance is insufficient

## How this service works

RSI, MACD, Bollinger Bands, SMA and EMA computed from any list of closing prices you supply, with plain-language overbought and trend signals.

## Output

Returns a JSON object with RSI (value + period), MACD (line, signal, histogram), SMA (value + period), EMA (value + period), Bollinger Bands, a bias string, bars count, and a plain-language note explaining how to interpret the signals. Fields are null when too few prices are supplied for a given indicator.
