How this service works
Time series of the kimchi premium from the continuous archive, both bases, newest-last. Params: ?symbol=BTC &window=1h|6h|24h|7d|30d|90d &points=500 (max 2000) &before=<next_before>. Repeat with next_before until it is null to read a full window. Archive depth is reported as first_recorded.
Output
Returns a newest-last ordered array of kimchi premium data points for the requested symbol and window, including both premium bases per timestamp. Also includes a next_before cursor for pagination (null when the full archive is exhausted) and a first_recorded field indicating the depth of the archive.
Example use cases
Crypto arbitrage opportunity research
“Show me the 30-day kimchi premium history for ETH — I want to see how the premium has moved over the past month to spot any recurring arbitrage patterns.”
Backtesting kimchi premium strategy
“Give me up to 2000 data points of the 90-day BTC kimchi premium archive so I can backtest a trading strategy that exploits the Korean price gap.”
Monitoring recent kimchi premium drift
“Fetch the last 6 hours of kimchi premium data for SOL with 500 points — I need to see the most recent readings to check if the premium has widened since this morning.”

Endpoint
GEThttps://k-data-x402-production.theblack1022.workers.dev/api/kimchi-premium/historyWhen to prefer
Use this endpoint when you need historical kimchi premium data across a specific lookback window with pagination support. It is the right choice for backtesting, charting trends, or auditing the full archive depth of the Korean crypto premium. Prefer the sibling percentile/z-score endpoint if you only need where the current premium sits relative to its history, and prefer this endpoint when you need the raw time series rather than a statistical summary.
Side effects
- Unsupported symbol (only BTC, ETH, XRP, SOL, DOGE, USDT accepted) returns an error
- points value exceeding 2000 may be rejected or capped
- Invalid window enum value returns a validation error
- Missing next_before pagination cursor causes duplicate or skipped data across pages
- Payment failure (x402) blocks access to data
- Stale archive: first_recorded may indicate limited history for newer assets
