```

Example prompt: What's the current market silence score for ETH over the last 7 days? I want to know if it's in one of those calm-before-the-move setups right now.

## When to prefer this

Use this endpoint when you need a single composite metric to quantify how quiet/silent a market is, particularly to identify pre-breakout compression setups. Prefer over raw volatility or volume endpoints when you want a unified 0-1 score combining multiple quietness signals. Pairs with /vol/compression-alert for alerting workflows.

## Known failure modes

- Unsupported asset symbol returns an error or empty result
- Invalid lookback period format (e.g. '30x' instead of '30d') causes a validation error
- Service unavailable or rate-limited when market data provider is down
- Score near 0.5 may be ambiguous — neither clearly silent nor active

## How this service works

Market-silence score 0-1 — a composite of low volume, low volatility and small price change. High silence often precedes expansion. Use to spot the calm-before-the-move. Pairs with /vol/compression-alert.

## Output

A 0-1 composite silence score reflecting how quiet the asset is across volume, volatility, and price change dimensions, plus component signals; a high score indicates unusual calm that often precedes a price expansion.
