API3 (API3) Real-Time Price & Kimchi Premium

What is the API3 kimchi premium and price gap?

API3 (API3) kimchi premium measures, as a percentage, how much more expensive the domestic exchanges (Upbit, Bithumb) are versus the Binance USDT price (adjusted by the live FX rate). The current API3 premium is -0.72%, which means the domestic price is lower than Binance (reverse premium). The current price on Upbit is ₩404.

Cross-exchange price gap is the price difference for the same coin between Bithumb and Upbit; the current API3 gap is -1.24%. Unlike the kimchi premium, the gap between domestic exchanges is an actual arbitrage zone, so MagnetChart tracks its convergence and divergence in real time.
