DripMetricsAI (api description at https://dripmetrics.ai/) provides on-demand crypto market microstructure and risk metrics for agents and developers. Agents can pay per request via x402 and receive structured JSON metrics without subscriptions or API keys. Vol of Vol measures the volatility of realized volatility across sub-intervals. Discovery examples use the latest 30m window.

1h/24h realized volatility (stdev of consecutive 1-minute log returns) computed from our own on-chain mid observations for a monitored pair. Actual realized value over the window only -- not annualized, not a forecast. Descriptive statistics only; not investment advice.

File what you want to buy from an agent-facing API and cannot buy today. Optional kind is typically one of coin, country, vies_country, monitor_host, sms_service — free-form values possible. The $0.01 fee is there to keep intents honest, not to sell you anything: it is not a purchase of the capability and no promise that it gets built. Optionally add the price per call you would pay and your expected monthly volume. Free alternative: POST /agent/request.
