DripMetricsAI (api description at https://dripmetrics.ai/) provides on-demand 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. VPIN measures volume-synchronized order-flow imbalance (an adverse-selection proxy, not a probability); see excessVpin. Discovery examples use the latest 30m window.
