## 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-snapshot-x402-13a76b08
```

Example prompt: What's the current kimchi premium right now — give me both the official FX basis and the USDT-KRW tradeable basis across Upbit and Bithumb.

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call, dual-basis kimchi premium with data from both Upbit and Bithumb simultaneously. Prefer it over scraping exchange APIs directly when you need normalized premium calculations on both the official USD/KRW FX basis and the USDT-KRW tradeable basis in a single call. Ideal for agents running periodic arbitrage scans or dashboards without a subscription commitment.

## Known failure modes

- Payment not included or invalid x402 USDC payment → 402 Payment Required
- Exchange data unavailable (Upbit or Bithumb API down) → partial or stale data returned
- Network timeout on worker → 503 or timeout error
- Invalid endpoint path → 404 Not Found
