## 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 deepsearch-crypto-real-time-price-coin-info-api-5b1f005e
```

Example prompt: What's the current Bitcoin price in Korean Won right now, including the kimchi premium, today's high and low, and trading volume?

## When to prefer this

Use this endpoint when you need real-time Korean market (KRW-denominated) cryptocurrency data, especially when the kimchi premium or KRX-context pricing is relevant. Prefer this over generic USD-based crypto APIs when the user is asking about Korean exchange prices, kimchi premium, or needs a full coin profile alongside live market metrics.

## Known failure modes

- Invalid or unsupported coin symbol returns an error or empty result
- Payment not processed (402 response if USDC micropayment fails)
- Network timeout if the real-time data source is temporarily unavailable
- Malformed request missing the required symbol query parameter
