## 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 kimchi-premium-statistical-distribution-stats-08b67247
```

Example prompt: Is the BTC kimchi premium unusual right now? Give me its percentile, z-score, and a plain-language read using the 24-hour window on the USDT basis.

## When to prefer this

Choose this endpoint when you need to know not just the raw kimchi premium value but how unusual or extreme it is in context — especially useful for automated trading signals, risk alerts, or reporting that requires statistical grounding. Prefer this over raw time-series endpoints when the question is 'is this premium elevated?' rather than 'what is the premium history?'

## Known failure modes

- Unsupported symbol returns an error (only BTC, ETH, XRP, SOL, DOGE, USDT are archived)
- Invalid window enum value returns a validation error
- Invalid basis value returns a validation error
- Insufficient archive data for very short windows may return degraded stats
- Payment failure via x402 protocol returns 402 status before data is delivered

## How this service works

Where the current kimchi premium sits inside its own recent distribution: percentile, mean, stdev, z-score, min/max/median, and a plain-language read. Answers 'is this premium unusual right now?' in one call. Built from a continuous archive that cannot be reconstructed from any free source. Params: ?symbol=BTC &window=1h|6h|24h|7d|30d|90d &basis=usdt|official.

## Output

Returns a JSON object containing the current kimchi premium's position within its own recent distribution: percentile rank, mean, standard deviation, z-score, minimum, maximum, median over the specified window, and a plain-language assessment of whether the premium is currently unusual — all computed from a proprietary continuous archive.
