prediction.watch
ActiveTool of Syenite
Registers a persistent background monitor for a specific Polymarket market that fires alerts when user-defined conditions are met. Supported conditions (at least one required): oddsThresholdPct (fire when implied probability crosses a target level), oddsMovePct (fire when probability moves by a delta% within a windowMinutes window), liquidityDropPct (fire when liquidity falls by a percentage from baseline), resolutionApproachingHours (fire when the market closes within N hours), and volumeSpikeMultiple (fire when 24h volume exceeds baseline by a multiple). Requires either slug or conditionId to identify the market (both returned by prediction.trending and prediction.search); optionally provide webhookUrl to receive POST payloads when conditions fire. Triggered alerts flow through alerts.check; use the returned watch ID with alerts.remove to stop monitoring. Does not place or cancel orders.
