# Kronos Market Intelligence — Calibrated Ranges by CoinOpAI

> Kronos Market Intelligence — Calibrated Ranges by CoinOpAI is a paid API for AI agents from x402.coinopai.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).

Returns empirically calibrated crypto forecast confidence bands, directional bias, and risk context for a given symbol and time horizon via x402 micropayment.

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-market-intelligence-calibrated-ranges-by-coinopai-a46fe3dd
```

Example prompt: I'm forecasting BTC over a 24-hour horizon with a raw confidence of 72% and an upward directional bias — can you run that through Kronos calibration and give me the empirical confidence band and calibration grade?

## When to prefer this

Choose this endpoint when you need empirically grounded, auditable confidence calibration for a crypto forecast — specifically when you have a raw confidence score and directional bias and want a statistically calibrated range with a historical hit rate. Prefer this over raw model outputs when decision journaling or post-decision auditability is required. It is distinct from simple price lookups or sentiment APIs because it applies Wilson-method empirical calibration to produce uncertainty bands rather than point estimates.

## Known failure modes

- Missing or invalid symbol returns 400 or empty result
- Payment not fulfilled via x402 returns 402 Payment Required
- Invalid directional_bias enum value causes validation error
- raw_confidence outside expected numeric range may produce unreliable banding
- Stale or missing calibration artifact causes degraded or offline uncertainty response
- Unsupported horizon string may return null or default calibration

## How this service works

Forecast confidence calibration. Returns raw_confidence, calibrated_confidence, confidence_band, historical_hit_rate, sample_size, calibration_grade, directional_bias, calibration data freshness, and liability disclaimers. Market intelligence only; no output is an instruction to trade, transact, hold, rebalance, or take market activity.

## Output

Returns a JSON object containing the ForgeMesh Calibration Engine version, empirical calibration method (Wilson), a confidence band with low/mid/high values, calibrated confidence score, calibration grade (e.g. 'fair'), historical hit rate percentage, directional bias, artifact age in minutes, and compliance/disclaimer metadata confirming market-intelligence-only use.
