## 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-conformally-calibrated-crypto-price-forecast-66e960a5
```

Example prompt: What's the Kronos conformally-calibrated 80% price prediction interval and upside probability for BTC right now?

## When to prefer this

Choose this endpoint when you need a statistically honest, calibrated uncertainty range for crypto price forecasts rather than a point prediction or directional signal. It is ideal for risk-aware agents that need to communicate uncertainty bounds to users, construct position sizing logic, or audit forecast reliability. Prefer it over raw directional signals when the agent must convey 'what range of outcomes is plausible' rather than 'which direction will price move'.

## Known failure modes

- Unsupported symbol returns an error — only BTC, ETH, SOL, XRP, ADA are supported
- Missing symbol query parameter may return a default or error response
- Payment failure (402) if USDC payment is not provided or is insufficient
- Service unavailability returns 5xx if the Kronos model pipeline is down
- Stale data if the underlying market data feed has not refreshed recently

## How this service works

Kronos by ForgeMesh calibrated crypto price forecast for BTC, ETH, SOL, XRP, and ADA. Returns its forecast horizon, current price, conformal 80% price range, point return, and upside probability for risk-aware autonomous agent planning. Updates hourly; paid in USDC on Base via x402.

## Output

Returns the ticker symbol, a range_80 object representing the empirically-calibrated 80% prediction interval for price movement, a point return estimate (noted as having no demonstrated directional edge), and an upside_probability float between 0 and 1 indicating the likelihood of a positive return.
