How this service works
Dual-basis KRW market intel for agents: kimchi premium on official-FX and USDT-KRW tradeable basis, two Korean exchanges, plain HTTPS JSON. Pay-per-call USDC on Base via x402 v2.
Output
A JSON object containing: the basis block with official USD/KRW FX rate, USDT/KRW rate on Upbit, and the USDT/KRW premium percentage; plus a symbols array where each entry has the coin symbol, its KRW price on Upbit, its global USD price, the kimchi premium on official FX basis (%), and the kimchi premium on USDT tradeable basis (%).
Example use cases
Crypto arbitrage opportunity scanner
“Check the kimchi premium for BTC, ETH, XRP, and SOL right now — I want to know both the official FX basis and the USDT basis so I can spot any arbitrage between Korean and global markets.”
Korean market price dashboard
“Pull the current Upbit KRW prices and kimchi premiums for BTC and DOGE, and tell me what the official USD/KRW and USDT/KRW rates are today.”
USDT-KRW spread monitoring alert
“What's the USDT/KRW premium percentage right now, and how does it compare to the official FX rate? I'm watching whether the USDT basis is diverging from the official rate.”

Endpoint
GEThttps://kimchi-x402.pn-26f.workers.dev/v1/kimchi/premium?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need dual-basis kimchi premium data (both official FX and USDT-tradeable) in a single call, paid per-use with no subscription. Ideal for agents doing arbitrage analysis, Korean market monitoring, or FX-adjusted crypto pricing — especially when you want the USDT/KRW spread alongside per-coin premiums. Prefer over generic crypto price APIs when Korean exchange pricing and kimchi premium specifically are the target.
Side effects
- Payment not received or invalid x402 USDC payment header — returns 402 Payment Required

- Too many symbols requested (over 20) — returns validation error
- Exchange API downstream outage — may return stale or partial data
- Malformed symbols query parameter — returns 400 Bad Request
