How this service works
Pay-per-call crypto technical analysis for AI agents (x402, USDC on Base). Daily trend regime, Donchian levels, ATR stops, signals and backtests computed with the code of a live trend-following bot from Binance spot klines.
Output
A JSON object containing the list of requested symbols, the number of lookback days used, and a square pairwise correlation matrix (values from -1 to 1) where each cell represents the return correlation between two assets. Example: {"days":60,"symbols":["BTCUSDT","ETHUSDT"],"matrix":[[1,0.82],[0.82,1]]}.
Example use cases
Portfolio diversification check
“I want to know how correlated BTCUSDT, ETHUSDT, BNBUSDT, and SOLUSDT have been over the last 90 days — show me the full correlation matrix so I can see if my portfolio is actually diversified.”
Pair trading candidate search
“Can you pull the 30-day correlation matrix for BTCUSDT, ETHUSDT, AVAXUSDT, and DOTUSDT? I'm looking for pairs with very high correlation that might be good candidates for a statistical arbitrage strategy.”
Risk assessment before adding a new coin
“I already hold BTCUSDT and ETHUSDT. How correlated is LINKUSDT with those two over the last 60 days? I want to know if adding it would actually reduce my concentration risk.”

Endpoint
GEThttps://vmi3089643.contaboserver.net/v1/correlationWhen to prefer
Choose this endpoint when you need quantitative pairwise correlation between crypto assets derived from actual Binance spot klines, especially within the context of a trend-following or portfolio-construction workflow. Prefer it over generic financial data APIs when you want correlation tightly integrated with the same data pipeline used for trend regime, Donchian levels, and ATR-based analysis on the same server.
Side effects
- Invalid or unrecognized symbol ticker returns an error or empty result
- Requesting too many symbols may cause timeout or oversized response
- Very short day windows (e.g. days=1) may return insufficient data
- Server unavailability on the Contabo VPS can cause connection timeouts
- Missing required 'symbols' or 'days' query params may return a 400 error
