## 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 swaphunt-expected-move-atr-based-price-range-12f85811
```

Example prompt: What are the ATR-based expected move bands for BTC/USDT on the daily timeframe — give me both the 68% and 95% probability ranges so I can set realistic stops and targets?

## When to prefer this

Use this endpoint when you need a statistically grounded, ATR-derived price range for a crypto asset rather than a directional prediction. Ideal for setting stops, targets, and breakout levels. Prefer this over raw volatility endpoints when you specifically need pre-computed probability bands (68%/95%) ready for trading decisions.

## Known failure modes

- Unsupported asset symbol returns an error or empty data
- Unsupported quote currency returns an error
- Invalid period string (not 4h, 1d, or 1w) returns a validation error
- Payment not received or insufficient USDC results in 402 Payment Required
- Upstream price/ATR data unavailable causes a 500 or timeout

## How this service works

ATR-based expected price range for the period: the 68% and 95% probability bands around current price. Use to set realistic targets, stops and breakout thresholds. A statistical range, not a directional forecast.

## Output

Returns the 68% and 95% statistical price bands (upper and lower bounds) around the current price for the requested asset/quote pair and period, derived from ATR. Not a directional forecast — a neutral probability range for use in position sizing, stop placement, and breakout level setting.
