## 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 genexxis-kimchi-premium-monitor-ab244fc4
```

Example prompt: What's the current kimchi premium for BTC, ETH, and XRP? I want to see the Upbit and Bithumb KRW prices compared to Binance, using the ECB USD/KRW rate, and how many percent premium each coin is trading at in Korea.

## When to prefer this

Choose this endpoint when you need to specifically measure the Korea crypto premium (kimchi premium) — the price difference between Korean exchanges (Upbit, Bithumb) and the global Binance USDT price, with an authoritative ECB-sourced USD/KRW conversion. It is ideal for crypto arbitrage research, Korea market monitoring, or cross-border price comparison. Use it over generic price APIs when the Korean market context and premium percentage are the primary concern.

## Known failure modes

- Invalid or unrecognized ticker symbols return errors in the errors array
- Requesting more than 30 symbols at once may be rejected
- ECB rate may be delayed or from prior business day on weekends/holidays
- Binance may not list all requested symbols, causing missing binanceUsdt values
- Network or exchange API downtime can cause stale or missing price data

## How this service works

Execution cost before trading crypto spot: walks the live public order books of Binance, Coinbase, Kraken, OKX and Bybit for a USD notional and returns average fill price, slippage vs mid in bps, worst price, fill status, best venue, and resting depth within 0.5 / 1 / 2% of mid per venue. Also the Korea ("kimchi") premium: Upbit and Bithumb KRW prices vs Binance USDT converted at the ECB USD/KRW rate. Live at request time (cache 10-15 s); failing venues listed in errors[].

## Output

Returns a JSON object with: an fx block containing the ECB USD/KRW rate and its reference date; a symbols array where each entry has the coin ticker, Upbit KRW price and 24h volume, Bithumb KRW price, Binance USDT price, USD-equivalent prices, and premium percentage for each exchange; a usdtKrw block showing the USDT premium on Upbit; and an errors array for any failed symbols.
