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 a two-sidedness score (float 0–1, where 1 = perfectly balanced), the YES and NO volumes, the dominant outcome, the number of trades sampled, the effective time window, the conditionId, a source URLs object pointing to Polymarket data, and a computedAt ISO timestamp.
Example use cases
Detect one-sided market manipulation
“Check the two-sidedness score for the Polymarket market 'will-trump-win-2024' over the last 120 minutes — I want to know if trading is heavily skewed toward one outcome or reasonably balanced.”
Pre-trade liquidity check for a bot
“Before my trading bot enters a position, can you pull the two-sidedness metric for Polymarket conditionId 0xdd22472e552920b8438158ea7238bfadfa4f736aa4cee91a6b86c39ead110917 over the last 30 minutes so I know whether there's real two-way flow?”
Dashboard monitoring for market health
“I'm building a prediction market dashboard — give me the two-sidedness score for the Polymarket slug 'us-recession-2025' using up to 500 trades so I can display a market health indicator.”
Technical details
Endpoint
POSThttps://api.dripmetrics.ai/polymarket/two-sidednessWhen to prefer
Choose this endpoint when you need a single scalar metric summarizing the balance of YES vs NO trading volume on a specific Polymarket market — especially useful for pre-trade liquidity checks, market health dashboards, or detecting one-sided manipulation. Prefer it over raw trade feeds when you want a pre-computed, normalized two-sidedness score rather than raw orderbook data.
Side effects
- Missing both conditionId and slug returns a 400 validation error
- Unknown or invalid conditionId/slug returns a 404 or empty result
- Insufficient trade data in the window yields a low sample size and possibly unreliable score
- windowMinutes too small may return zero trades
- Limit exceeding 5000 is rejected by schema validation
- Payment failure (x402) returns a 402 if USDC balance is insufficient
