kr-crypto-intelligence

KR Crypto Intelligence is a South Korean cryptocurrency market data and AI analysis API for AI agents, provided by the GitHub repository bakyang2/kr-crypto-intelligence. Its core goal is to output localized data from the South Korean crypto market (kimchi premium, exchange prices, exchange rates, Korean news sentiment) in English, for direct use by AI trading agents or analysis tools.

Purpose and Positioning The service is aimed at AI agents that need South Korean market information, especially arbitrage and trading analysis scenarios. It emphasizes the particularities of the South Korean market data: there is a structural premium difference of 0.3%-1% between the official USD-KRW benchmark and the actual USDT trading benchmark. The official benchmark may be misleading; only the USDT benchmark can reflect the true arbitrage space after deducting capital flow costs.

Main Capabilities The service includes 16 paid endpoints, divided into several categories:

1. Kimchi premium and arbitrage: provides dual-benchmark kimchi premium (official USD-KRW benchmark and actual USDT trading benchmark), covering 189+ tokens listed simultaneously on Upbit and Binance, supports reverse premium detection (Korean discount regarded as a buy signal), Upbit and Bithumb spread scanning, and market share tracking.
2. Korean sentiment analysis: claims to be the world's first Korean-to-English crypto sentiment API, combining exchange data (189+ token kimchi premium, warnings, volume spikes, deposit spikes) with Korean news context (Coinness Telegram, 6-hour window), with Claude AI generating sentiment labels (BULLISH/BEARISH/CAUTIOUS_FOMO/PANIC/GREED/UNCERTAIN), a score from -1.0 to +1.0, English reports, exchange signals, news context, and sources. It uses a 1-hour cache, lazy invocation, and concurrency locks to control costs.
3. Exchange intelligence and alerts: new listing/delisting detection (compares market lists every 60 seconds), investment warning flags, alerts for price volatility/volume spikes/deposit spikes/global price spreads/concentration in small accounts, 1-minute price surge and crash detection (more than 1% within 60 seconds), volume spike detection (24-hour change rate, volume exceeding 1 billion KRW), top 20 tokens by volume.
4. AI analysis: integrates 12+ data sources (kimchi premium, stablecoin premium, exchange rates, Upbit/Bithumb top 5 by volume, BTC funding rate, open interest, dominance, fear and greed index, exchange intelligence, etc.), with Claude AI generating signals (BULLISH/BEARISH/NEUTRAL), 1-10 confidence, summaries, key factors, token-level alerts, and risk warnings.
5. KRW macro signals and English translation of Korean news: provided as newly added endpoints.
