## 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-x402-krw-market-intel-3babcc35
```

Example prompt: What's the kimchi premium right now, and which coins are leading volume on Upbit and Bithumb — give me both the official FX basis and the USDT-KRW tradeable basis?

## When to prefer this

Choose this endpoint when you need live KRW-denominated crypto pricing from Korean exchanges (Upbit, Bithumb) specifically, or when you need the kimchi premium expressed in both official-FX and USDT-KRW tradeable terms. Prefer this over generic global market data APIs when Korean market arbitrage, KRW pricing, or cross-border crypto spread analysis is the goal. Its pay-per-call USDC pricing via x402 makes it suitable for agent workflows without subscription setup.

## Known failure modes

- Upstream exchange API unavailable — returns empty arrays for affected exchange
- Payment not settled via x402 — 402 Payment Required response
- Malformed JSON response if worker encounters an unhandled exchange API format change
- Stale data if exchange rate feeds are delayed

## How this service works

## Output
