## 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-eth-price-forecast-api-cc7c9a02
```

Example prompt: What does Kronos predict for ETH over the next 4 hours — give me the up-probability, expected close, and p10–p90 price range.

## When to prefer this

Choose this endpoint when you need ML-generated directional probability and quantile-bounded price forecasts for ETH specifically, with a verifiable live track record (not a backtest). Prefer this over generic price feeds when you need uncertainty quantification (p10–p90 range, volatility) rather than just spot price. Best for trading bots and risk management agents that need actionable probability scores, not just market data.

## Known failure modes

- Invalid horizon value returns 400 error — must be one of: 1h, 4h, 24h
- Payment failure or insufficient USDC balance on Base returns 402 Payment Required
- Model cache miss or upstream data feed delay may return stale or unavailable data
- Rate limiting if too many calls are made without proper x402 payment flow

## How this service works

Real-time and ML-forecasted Ethereum (ETH) price. Kronos deep-learning model: up-probability, expected close, price range, p10-p90 quantiles, forward volatility across 1h/4h/24h horizons. Crypto price prediction / price forecast API for AI agents and trading bots. Pay-per-call via x402 on Base USDC. Live track record at /api/stats: ~54% directional hit, ~70% in-range over 15k+ scored forecasts — measured on served predictions, not a backtest.

## Output

JSON object containing current ETH spot price, ML-model up-probability (likelihood of price increase), expected close price, forecast price range, p10–p90 quantile bands, and forward volatility — all calibrated for the requested horizon (1h, 4h, or 24h). Live track record shows ~54% directional accuracy and ~70% in-range rate across 15,000+ scored forecasts.
