## 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-by-forgemesh-crypto-market-forecast-x402-625e8bf5
```

Example prompt: What's Kronos's calibrated 80% price range and upside probability for BTC/USD right now?

## When to prefer this

Choose this endpoint when an AI agent needs a statistically calibrated, probabilistic price range for a crypto asset rather than a raw price quote or sentiment signal. It is particularly suited for autonomous trading agents that need a structured risk state and signal context before executing or gating a trade, and for workflows that support x402 micropayment on Base for per-call billing.

## Known failure modes

- Missing or invalid symbol query parameter returns an error or empty result
- Payment not fulfilled via x402 results in 402 Payment Required response
- Symbol not supported by the service returns an error or no forecast
- Network/service unavailability returns a 5xx error
- Stale market data may reduce forecast reliability during low-liquidity periods

## How this service works

Paid crypto market-intelligence API for autonomous agents. Calibrated ranges, signal context, risk state, decision journals, and outcome audits via x402 micropayments on Base.

## Output

Returns a JSON object with: the queried symbol, forecast horizon (~5h), an 80% calibrated price range (low/high) computed via conformal prediction, the current price, upside probability (0-1), and contextual notes explaining range caveats (why_not_high array).
