DripMetricsAI (https://dripmetrics.ai/) provides on-demand order-book microstructure metrics computed fresh per request from Binance's public depth snapshot. Agents can pay per request via x402 and receive structured JSON metrics without subscriptions or API keys. Imbalance is (bid volume - ask volume) / (bid volume + ask volume) over the top depthLevels on each side.
