Crypto Risk Profile (VaR & Tail Risk) API

The full risk scorecard of any coin, computed live from its Binance daily candles — no key, nothing stored. Volatility alone hides what matters most for risk: the tails. This returns the Value at Risk (the daily loss not exceeded on 95% / 99% of days), the Conditional VaR / expected shortfall (the average loss on the worst days, beyond VaR), the skewness and excess kurtosis of the return distribution (how asymmetric and how fat-tailed it is — crypto is famously fat-tailed), the maximum drawdown, and the risk-adjusted return ratios (Sharpe and Sortino). The profile endpoint returns the whole scorecard for one coin; the drawdown endpoint returns the worst peak-to-trough decline with its peak, trough and depth plus the current drawdown from the high; the compare endpoint ranks a basket of coins by risk-adjusted return so you can see which carries the most tail risk per unit of return. This is the coin-native risk-distribution / tail-risk cut for crypto — distinct from the generic risk-metrics, CAPM and trade-stats APIs (which compute on a series you pass in) and from the realised-volatility API (which has no VaR, skew, kurtosis or drawdown). Coins are Binance bases (BTC) or symbols (BTCUSDT); the quote defaults to USDT and the window is 30-1000 days. Risk-free rate is assumed 0.
