Example prompt: What's the current KRW price, market cap, and kimchi premium for BTC on the Korean crypto market right now?

## When to prefer this

Use this endpoint when you need real-time Korean market (KRW) cryptocurrency pricing, especially when the kimchi premium or Korean market cap data is relevant. Ideal for comparing Korean vs global crypto prices, monitoring KRW-denominated portfolios, or analyzing arbitrage opportunities specific to the Korean crypto market.

## Known failure modes

- Invalid or unsupported coin symbol returns an error or empty result
- Payment failure (insufficient USDC on Base Mainnet) prevents the query from executing
- Network timeout or service unavailability returns a 5xx error
- Symbol provided in wrong format (e.g. lowercase or with special chars) may not resolve correctly

## How this service works

Up to 10 years of financials + 3 years of daily price history for all 2,000+ KRX stocks. Pay-per-query with USDC on Base Mainnet — no subscription.

## Output

A JSON object containing the coin symbol, current trade price in KRW, percentage change rate, English name, total market cap in KRW (formatted in Korean units like 조원), and the kimchi premium (the price gap between Korean and global markets as a percentage).
