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
A structured JSON object containing a leakage score value, component breakdown (probability shock, flow imbalance, etc.), the analysis window used, sample size of trades evaluated, the inferred or provided event anchor timestamp, and data source metadata.
Example use cases
Example prompt
“Can you pull the leakage score for the Polymarket market with slug 'will-fed-cut-rates-july-2025', YES outcome, looking back 120 minutes with a 60-minute window, and tell me if there was unusual pre-event flow?”
Technical details
Endpoint
POSThttps://api.dripmetrics.ai/polymarket/leakage-scoreWhen to prefer
Use this endpoint when you need to quantify whether a Polymarket prediction market exhibited statistically unusual price or flow movement before a known or inferred event — i.e., to detect information leakage, front-running, or insider trading signals. Prefer this over generic price history queries when you specifically need a normalized leakage diagnostic score with component breakdown rather than raw price data.
Side effects
- Missing required identifiers (conditionId+tokenId, conditionId+assetId, or slug+outcome) returns a 400 validation error
- Invalid or unknown conditionId/tokenId/slug returns a 404 or empty result
- Insufficient trade data in the window returns a low-confidence or null leakage score
- Payment not provided or insufficient USDC via x402 returns a 402 Payment Required
- windowMinutes or lookbackMinutes set too small may produce unreliable normalization
- Ambiguous multi-market event slug without conditionId may return wrong market data
