## 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 api-printmoneylab-com-bf653915
```

Example prompt: What's the current kimchi premium for ETH — how much more expensive is it on Upbit compared to Binance right now?

## When to prefer this

Use this endpoint when you need a fast, single-token kimchi premium calculation without the overhead of the full 189+ token bulk endpoint. Ideal for real-time arbitrage monitoring, alerting on a specific coin, or when only one token's Korea-vs-global price gap is needed.

## Known failure modes

- Missing required 'symbol' query parameter — returns validation error
- Symbol not listed on Upbit or Binance — returns not found or null premium
- FX rate service unavailable — may return error or stale data
- Rate limiting or payment failure (x402) — returns 402 Payment Required
