How this service works
Equity-curve summary of a price or return series you supply: CAGR, volatility, Sharpe, drawdown, best and worst period.
Output
Returns a structured JSON object with: CAGR (%), annualized volatility, Sharpe ratio, Sortino ratio, Calmar ratio, maximum drawdown (with peak/trough indices), best and worst period returns, start and end values, number of periods, elapsed years, a human-readable summary/verdict, and optional warnings or degraded-quality flags if inputs are too short or degenerate.
Example use cases
Backtested strategy performance review
“I ran a backtest and have these 60 monthly price values: [100,102,101,105,107,106,110,112,111,115,118,116,120,122,121,125,128,126,130,132,131,135,138,137,140,142,140,145,148,147,150,153,152,155,158,156,160,163,162,165,168,167,170,173,172,175,178,177,180,183,182,185,188,187,190,193,192,195,198,200]. Can you give me the full equity curve summary — CAGR, Sharpe, Sortino, Calmar, max drawdown, best and worst month — using 12 periods per year and a 2% risk-free rate?”
Weekly returns risk-adjusted stats
“I have these weekly portfolio returns in decimal form: [0.01, -0.005, 0.02, 0.015, -0.01, 0.03, -0.008, 0.012, 0.025, -0.015, 0.018, 0.022]. Can you compute the full equity curve stats — CAGR, volatility, Sharpe, and max drawdown — using 52 periods per year and a 3.5% annual risk-free rate?”
Comparing fund performance metrics
“I'm comparing two funds and need the standard equity-curve metrics for fund A's daily prices: [50, 50.5, 49.8, 51, 52.3, 51.5, 53, 54.2, 53.8, 55, 56.1, 55.5, 57, 58, 57.2, 59, 60.5, 59.8, 61, 62]. Use 252 periods per year and 5% risk-free rate — I need CAGR, Sharpe, Sortino, drawdown, and best/worst day.”
Technical details
Endpoint
GEThttps://portfolio-stats.x402tookit.com/equity-curve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single call that returns the full suite of equity-curve performance metrics at once — CAGR, Sharpe, Sortino, Calmar, drawdown, and best/worst period — rather than calling individual sibling endpoints for each statistic separately. Ideal when summarizing a strategy, fund, or portfolio for reporting or comparison purposes and you want one comprehensive result object.
Side effects
- Fewer than 2 data points provided — returns error or degraded result
- Both prices and returns supplied simultaneously — ambiguous input rejected
- Invalid JSON format in prices or returns query parameter
- periodsPerYear set to 0 or negative — causes division errors
- All returns are identical or zero — Sharpe/Sortino undefined
- Input series longer than 1000 periods — truncated or rejected
- Network or payment failure returns 402/503
