How this service works
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. VRP measures the intraday variance risk premium: shortest-dated Deribit ATM implied variance minus DripMetrics' annualized trade-level realized variance over the requested window.
Output
A structured JSON object containing: the metric name ('VRP'), the asset pair ('BTC'), the computed VRP value (implied variance minus realized variance, annualized), a components object breaking out the implied and realized variance legs, the lookback window used, sample size details, source attribution (Deribit + DripMetrics), and a UTC timestamp of when the metric was computed.
Example use cases
Example prompt
“What's the current BTC variance risk premium right now? Use the 1-hour lookback window so I can see how much the Deribit ATM implied variance is exceeding the realized variance from recent trades.”

Endpoint
GEThttps://api.dripmetrics.ai/options/vrpWhen to prefer
Choose this endpoint when you need a real-time, on-demand BTC variance risk premium that combines live Deribit implied volatility with DripMetrics' proprietary trade-tape realized variance — especially when you want a pay-per-call model with no subscription or API key, and when intraday granularity (30m–3h windows) matters for timing options trades or monitoring vol risk premium regimes.
Side effects
- Insufficient trade data in the requested window returns null value for VRP or reduced sample size
- Deribit option chain unavailable may cause computation failure or partial result
- Invalid window parameter (not one of 30m, 1h, 2h, 3h) returns a validation error
- Payment not provided or insufficient USDC triggers a 402 Payment Required response
- No shortest-dated ATM options available (e.g. expiry gap) may cause null implied variance component
