## 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-x402-api-eth-snapshot-44ed16b9
```

Example prompt: Pull me the latest Kronos snapshot for ETH — I want the current spot price, the ML forecast up-probability and expected price range for the next hour, and any active regime alerts or derivatives signals like funding rate and open interest.

## When to prefer this

Choose this endpoint when you need a single bundled ETH market-intelligence payload combining spot price, ML directional forecast, derivatives metrics, and regime alerts in one call — rather than querying separate endpoints for each signal. Ideal for trading assistants or portfolio agents that need fast, structured ETH context without assembling multiple data sources. The x402 micropayment model means no API key management; pay per call at $0.08 USDC.

## Known failure modes

- 402 Payment Required if x402 payment header is missing or insufficient
- Stale data if upstream Binance or Deribit feed is delayed
- Forecast unavailable flag if ML model cache has expired
- Empty active_alerts array when no regime conditions are triggered (not an error)
- Network timeout if kronossignals.com is unreachable

## How this service works

Full crypto asset snapshot in one call (all 16 assets): real-time Binance spot price, derivatives (funding rate, OI, basis from Bybit/OKX perp), market regime alerts (BTC only). FORECASTS: BTC/ETH/SOL only (Kronos ML coverage). DERIVATIVES DATA: all 16 assets. Bundle replaces 3 separate paid calls — $0.08 vs $0.09 à la carte. For AI agents & trading bots. Live track record at /api/stats: ~54% hit over 15k+ scored forecasts, not a backtest.

## Output

A JSON snapshot containing: as-of timestamp, asset identifier, spot price (from Binance), derivatives data (funding rate, annualized rate, funding trend, basis, mark price, open interest), ML forecast (model name, horizon, up-probability, range low/high, expected close), market regime state (current state description, active alerts), and a disclaimer. All wrapped in a structured JSON object with an availability flag per sub-section.
