## 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 agent-signals-volatility-crypto-volatility-regime-signal-90a38673
```

Example prompt: What's BTC's current volatility regime — is it normal, high, or low — and what's the annualized realized vol right now?

## When to prefer this

Use this endpoint when an AI trading agent needs to assess whether a crypto asset is in a high, normal, or low volatility regime before sizing positions, adjusting stop-losses, or deciding whether to trade at all. Prefer this over generic price feeds when the key question is vol regime classification rather than raw price data.

## Known failure modes

- Missing or invalid symbol parameter returns an error or empty response
- Unsupported asset symbol may return null data or an error
- Payment not settled via x402 returns HTTP 402 Payment Required
- Network timeout or upstream data unavailability returns 5xx error

## How this service works

Pay-per-call crypto market-intelligence API for autonomous AI trading agents. Funding-rate, BTC lead-lag and trend/chop regime signals, settled in USDC over x402.

## Output

A JSON object with the asset base symbol, 1-hour ATR as a percentage, a volatility regime label (e.g. 'normal'), annualized realized volatility percentage, and a human-readable interpretation string summarizing the current vol environment.
