How this service works
DripMetricsAI (https://dripmetrics.ai/) provides on-demand crypto market microstructure metrics, Hyperliquid candle metrics, Polymarket diagnostics, and on-chain DefiLlama metrics for agents, dashboards, and trading workflows.
Output
Returns a JSON object containing the metric name ('downside-semivolatility'), the computed floating-point value, the trading pair, exchange, lookback window, computation timestamp, total trade count used, first and last trade timestamps, and a coverage object detailing whether the full window was captured (requested vs effective minutes, coverage ratio, partial data flag, and any error message).
Example use cases
Pre-trade downside risk check
“Before I enter a long BTC position, can you pull the downside semi-volatility for BTC-USD on Coinbase over the last 30 minutes so I know how choppy the downside has been?”
Automated strategy risk filter
“Every hour, check the downside semi-volatility for BTCUSDT on Binance over a 1h window and alert me if it spikes above 0.5 so I can tighten my stop-loss.”
Comparing exchanges for execution
“Can you get me the downside semi-volatility for BTC-USD on Coinbase and BTCUSDT on Binance over the last 2 hours so I can see which venue has been riskier on the downside?”
Technical details
Endpoint
GEThttps://api.dripmetrics.ai/metrics/downside-semivolatilityWhen to prefer
Choose this endpoint when you need a precise, real-time downside semi-volatility metric computed from actual recent trades on Binance or Coinbase — particularly useful for risk-adjusted trading strategies, pre-trade risk checks, or dashboards that need one-sided volatility rather than symmetric volatility. Prefer this over generic volatility endpoints when you specifically care about negative return dispersion or downside deviation.
Side effects
- Invalid or unsupported trading pair symbol returns an error
- 2h and 3h windows only supported for BTCUSDT/BTC-USD; other pairs return an error or partial data
- Exchange adapter unavailability may result in partial coverage (coverageRatio < 1, partialData: true)
- Insufficient trade data within the window results in low tradeCount and potential computation inaccuracy
- Payment failure or missing x402 payment header returns 402 Payment Required
