How this service works
DripMetricsAI (https://dripmetrics.ai/) provides on-demand crypto market microstructure metrics, Hyperliquid candle metrics, Polymarket diagnostics, and on-chain DefiLlama metrics for agents, dashboards, and trading workflows.
Output
Returns a JSON object with the computed Kyle's Lambda value (price impact per unit signed order flow), regression components including alpha, r-squared, number of intervals, mean signed order flow, last price, dollars per 1 cent move, plus trade count and the time window of trades used for the computation.
Example use cases
Example prompt
“What's the Kyle's Lambda price impact metric for BTCUSDT on Binance over the last 1 hour — how much does a unit of signed order flow move the price?”
Technical details
Endpoint
GEThttps://api.dripmetrics.ai/metrics/kyle-lambda?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a rigorous, regression-based measure of market price impact and order flow sensitivity for crypto pairs on Binance or Coinbase. Prefer this over simple spread or volume metrics when building execution algorithms, market-making bots, or risk models that need to quantify how much signed order flow moves prices. It is pay-per-use via x402, requiring no subscription or API key setup.
Side effects
- Unsupported exchange or pair combination returns an error
- Insufficient trade data for the window may produce unreliable r-squared
- Invalid pair symbol format causes a 400-level error
- x402 payment failure or insufficient USDC balance blocks the request
- Window enum values other than 30m or 1h are rejected
