# Kronos BTC Regime Indicator

> Kronos BTC Regime Indicator is a paid API for AI agents from api.nexismvp.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Returns the current Bitcoin market regime (calm or volatile) based on realized volatility, using the same signal as the Kronos regime-switching trading strategy.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 kronos-btc-regime-indicator-798c1576
```

Example prompt: What's the current Bitcoin market regime — is BTC in a calm or volatile state right now, and what's the realized volatility reading behind that signal?

## When to prefer this

Choose this endpoint when you need a simple, binary regime classification (calm vs volatile) for BTC based on realized volatility — particularly useful for regime-conditional strategies, risk filters, or dashboard indicators. Prefer this over raw price feeds or fear/greed indices when you specifically need a volatility-regime signal rather than directional price forecasts or sentiment scores.

## Known failure modes

- API unavailability returns a non-200 HTTP error
- Stale or delayed data if upstream volatility source is lagging
- No authentication failure modes documented but x402 payment failure would block access
- Empty or malformed response if the underlying data feed is disrupted

## How this service works

Real-time BTC volatility/regime indicator (calm or volatile), the same signal our own regime-switching strategy uses internally. Experimental/informational only — not financial advice.

## Output

Returns a JSON object with: the BTC symbol, realized volatility (numeric), the current regime classification ('calm' or 'volatile'), and the threshold value used to determine the regime boundary.
