# Kimchi premium (Korean spot vs. global BTC price)

`GET /api/v1/kimchi-premium`

## Request

- Base URL: `https://tradingstrategies.work`
- URL: `https://tradingstrategies.work/api/v1/kimchi-premium`
- Auth: HTTP bearer

Daily Kimchi-premium snapshots: Upbit BTC/KRW (USD-converted) versus the global BTC/USD price, in percent — one point-in-time reading per UTC day (~01:45 UTC), both legs from the same price/FX source (CoinGecko) so the ratio is internally consistent. Positive = Korean premium, negative = discount. The series is collected forward-only since 2026-08 and cannot be backfilled — early on n_days is small and the payload says so. Window via `days`, tier-capped (Free 30d, Pro 365d, Power 3650d); the `range` block declares requested vs. granted.
