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 flow imbalance score (a number between -1 and 1 indicating directional pressure), yes and no volumes, total volume, trade count, the Polymarket condition ID, the time window used, source URLs for the underlying market and trade data, and a timestamp of when the metric was computed.
Example use cases
Pre-trade directional bias check
“Before I put in a trade on the 'us-recession-2025' Polymarket market, can you check the flow imbalance over the last 30 minutes so I can see if there's strong buying pressure on one side?”
Prediction market sentiment dashboard
“I'm building a dashboard — pull the flow imbalance for the 'fed-decision-in-october' Polymarket market over the past 60 minutes and give me the yes volume, no volume, and trade count breakdown.”
Detect unusual trading activity
“Check if there's any unusual one-sided flow imbalance on the 'trump-wins-2024' Polymarket market in the last 15 minutes — I want to know if it's spiking above 0.3 in either direction.”
Technical details
Endpoint
POSThttps://api.dripmetrics.ai/polymarket/flow-imbalanceWhen to prefer
Use this endpoint when you need real-time directional flow analysis for a specific Polymarket prediction market — particularly when you want to understand whether buy-side or sell-side pressure dominates within a recent time window. It is purpose-built for Polymarket microstructure diagnostics, unlike generic sentiment or price feeds. Prefer it over raw Polymarket API calls when you need pre-computed, normalized flow imbalance metrics ready for agent consumption or dashboard integration.
Side effects
- Unknown or misspelled market slug returns an error or empty result
- Market with insufficient trade history in the requested window returns low sample size or null
- Very short time windows (e.g. 1 minute) may return sparse data with unreliable imbalance scores
- Network issues reaching Polymarket's Gamma API or Data API may cause upstream fetch failures
- Payment failure via x402 protocol prevents the request from being processed
