DripMetricsAI (https://dripmetrics.ai/) provides on-demand BTC option-derived metrics that combine the Deribit option chain with DripMetrics' own trade-level realized calculations. Agents can pay per request via x402 and receive structured JSON metrics without subscriptions or API keys. Crash premium measures Deribit 25-delta risk-reversal skew minus the realized downside-upside semivolatility asymmetry on DripMetrics' BTC trade tape, both in annualized vol points.
