# SwapHunt Bollinger-Band Squeeze / Volatility Compression Alert

> SwapHunt Bollinger-Band Squeeze / Volatility Compression Alert is a paid API for AI agents from x402.swaphunt.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Detects Bollinger Band squeezes on a chosen asset and timeframe, returning a compression severity level (extreme/strong/moderate/none) plus bandwidth to anticipate volatility expansions and breakouts.

## 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-bollinger-band-squeeze-volatility-compression-alert-f29db2e8
```

Example prompt: Is BTC/USDT in a Bollinger Band squeeze right now on the 4h chart — and how severe is the compression? I want to know if volatility is coiling up for a breakout.

## When to prefer this

Use this endpoint when you need to identify whether a Bollinger Band squeeze is forming on a specific crypto asset and timeframe — particularly useful for pre-breakout detection, volatility regime analysis, or timing entries before a big move. Prefer this over general volatility endpoints when you specifically need squeeze severity classification and bandwidth metrics rather than raw ATR or historical volatility stats.

## Known failure modes

- Unknown asset symbol returns an error or empty result
- Unsupported timeframe value causes validation failure
- Quote currency not available for the requested pair returns an error
- Service unavailable or payment rejected returns 402 or 5xx
- Stale market data may cause delayed or inaccurate compression readings

## How this service works

Bollinger-Band squeeze detector: is volatility compressing toward a likely expansion? Returns extreme/strong/moderate/none plus bandwidth. Use to anticipate breakouts before they fire. Detects the setup, not the direction.

## Output

Returns a compression severity label (extreme, strong, moderate, or none), the current Bollinger Band bandwidth value, and enough context to assess whether a volatility expansion or breakout setup is forming — without predicting direction.
