## 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-signals-btc-forecast-path-fan-b4e1898e
```

Example prompt: What's the Kronos Monte Carlo forecast fan for Bitcoin right now — give me the p10 through p90 quantiles and expected close at the 1h, 4h, and 24h horizons, plus the forward volatility estimates?

## When to prefer this

Use this endpoint when you need a full probabilistic forecast fan for Bitcoin price — not just a point estimate — with distinct quantiles to reason about upside/downside risk. Prefer it over simple price endpoints when building risk-aware trading signals, scenario analysis, or agent reasoning about BTC uncertainty over multiple time horizons. Choose this over the broader market screener when you specifically need BTC path distribution detail.

## Known failure modes

- Payment not provided or insufficient (402 Payment Required)
- Monte Carlo simulation data temporarily unavailable due to refresh cycle gap
- Rate limit exceeded for the endpoint
- Invalid or malformed request parameters
- Service downtime causing 503 response

## How this service works

Kronos forecast path fan for BTC/ETH/SOL: p10/p25/p50/p75/p90 quantiles, expected close and forward volatility at 1h, 4h and 24h horizons, from 60-path Kronos-base Monte-Carlo runs refreshed every 20 min. Discrete-horizon distributions (no interpolation). Informational only, not financial advice. Live track record at /api/stats: ~54% directional hit, ~70% in-range over 15k+ scored forecasts — measured on served predictions, not a backtest.

## Output

Returns a discrete-horizon probability distribution for BTC price: five quantile paths (p10, p25, p50, p75, p90), an expected close price, and forward volatility estimates at 1-hour, 4-hour, and 24-hour horizons, derived from 60-path Monte Carlo simulation refreshed every 20 minutes. No interpolation between horizons.
