How this service works
The "kimchi premium" — how much higher a crypto asset trades on Korean exchanges (Upbit, KRW) than its global USD price, as a percent. Computed as (Upbit KRW price / (global USD price × USD/KRW)) − 1. Pass symbol = ticker(s), comma-separated up to 10 (default BTC); supported majors include BTC, ETH, XRP, SOL, DOGE, ADA, TRX and more. Returns per symbol { krwPrice, usdPrice, usdKrw, globalUsdInKrw, premiumPct }. Per-symbol resilient (one unlisted symbol does not fail the rest); unresolved symbols are reported in meta.errors. Live blend of Upbit (KRW price) + CoinGecko (global USD) + ECB/Frankfurter (USD/KRW FX).
Output
Per-symbol object containing krwPrice (Upbit KRW price), usdPrice (global USD price from CoinGecko), usdKrw (USD/KRW FX rate from ECB/Frankfurter), globalUsdInKrw (global USD price converted to KRW), and premiumPct (Korean premium as a decimal/percentage). Also includes meta.errors listing any unresolved symbols that did not fail the overall request.
Example use cases
Example prompt
“What's the current kimchi premium for BTC, ETH, and XRP — how much higher are they trading on Korean Upbit compared to their global USD price?”
Technical details
Endpoint
GEThttps://2s.io/api/crypto/kimchi-premiumWhen to prefer
Use this endpoint when you need real-time kimchi premium data (Korean crypto price premium) across major assets like BTC, ETH, XRP, SOL, DOGE, ADA, TRX. Ideal for arbitrage monitoring, cross-market crypto analytics, or any use case comparing Korean Upbit KRW prices against global USD prices with live FX adjustment. Prefer over manual calculation since it blends three live data sources (Upbit, CoinGecko, ECB FX) atomically.
Side effects
- Symbol not listed on Upbit — reported in meta.errors but does not fail other symbols
- Invalid or unsupported ticker — included in meta.errors
- CoinGecko or Upbit API unavailability causing partial or full data failure
- FX rate fetch failure from ECB/Frankfurter causing computation to fail
- More than 10 symbols passed — likely truncated or rejected
- Empty symbol param — defaults to BTC
