How this service works
Historical crypto trend and realized-volatility statistics for BTC, ETH, BNB, SOL, XRP, DOGE, ADA, and LINK across 30-180 day lookbacks and 5m/15m/1h bars. Use for trend persistence, volatility, drawdown, and regime-context research before strategy selection or portfolio review. Returns returns, range, annualized volatility, max drawdown, OLS trend slope and R², methodology, and request metadata.
Output
A JSON response containing historical return statistics, price range, annualized realized volatility, maximum drawdown, OLS trend slope and R² goodness-of-fit, methodology description, and request metadata (symbol, lookback, bar resolution, timestamp).
Example use cases
Pre-trade regime context for BTC
“Before I enter a BTC position, give me a 60-day historical volatility and trend persistence summary using 15-minute bars — I want annualized vol, max drawdown, and the OLS slope with R² so I can gauge if BTC has been trending cleanly.”
Portfolio review across altcoins
“I'm reviewing my altcoin portfolio — can you pull 180-day realized volatility and max drawdown stats for SOL, ADA, and LINK using hourly bars so I can compare their risk profiles side by side?”
Strategy selection regime check for DOGE
“I'm trying to decide whether a trend-following or mean-reversion strategy makes more sense for DOGE right now — fetch the 90-day OLS trend slope, R², and annualized volatility using 5-minute bars to help me figure out the regime.”
Technical details
Endpoint
POSThttps://base.46-225-15-169.sslip.io/v1/trend-volatilityWhen to prefer
Use this endpoint when you need backward-looking, quantitative regime context — realized volatility, trend slope, drawdown — for one of the eight supported major cryptocurrencies before making strategy or portfolio decisions. Prefer this over real-time snapshot endpoints when you need statistical depth (OLS regression, R², annualized vol) over a configurable multi-day lookback rather than a current market snapshot.
Side effects
- Unsupported symbol returns a 400 or error payload
- Lookback period outside 30-180 day range may return validation error
- Unsupported bar resolution (not 5m/15m/1h) returns error
- Insufficient historical data for requested lookback may return partial or error response
- Service unavailable or upstream data feed outage returns 5xx
- Payment not processed (x402) results in 402 response blocking data return
