How this service works
Insider-style trade detection on Polymarket: scans the latest large fills (min_usd, default 10000 USD) over lookback_hours (default 24) and flags wallets that are fresh (few lifetime trades), sized big vs the market 24h volume, or entered at extreme odds right before the market moved.
Output
Returns a JSON object with a count of flagged alerts and an array of alert objects, each containing the transaction hash, wallet address, trade side, size in USD, entry price, market name and slug, outcome, UTC timestamp, severity score (0-100), list of suspicion reasons (e.g. fresh wallet, oversized vs market volume, extreme odds entry), wallet lifetime trade count, and 24h market volume and price change. Also includes methodology notes, total fills scanned, and the parameters used.
Example use cases
Front-running detection before event resolution
“Check Polymarket for any suspicious large fills in the past 6 hours — trades over $50,000 — and flag any fresh wallets that entered at extreme odds right before the market moved. Show me up to 20 alerts.”
Daily insider radar digest for a trading bot
“Run the insider radar on Polymarket for the last 24 hours with a minimum trade size of $10,000 and give me up to 25 flagged wallets so I can decide whether to mirror any of these positions.”
Weekly deep scan for smart money signals
“Do a 7-day lookback on Polymarket for whale trades above $30,000, return up to 50 alerts, and highlight wallets that look like they had an information edge based on their trading history and timing.”
Technical details
Endpoint
POSThttps://insider-radar.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need on-chain behavioral signals specifically from Polymarket and want pre-scored anomaly detection rather than raw fill data. It is ideal for agents monitoring prediction markets for smart-money flow, building trading strategies that follow information-advantage wallets, or performing market surveillance. Prefer this over generic blockchain explorers when you need pre-computed severity scores and multi-factor reasons (wallet freshness, sizing vs volume, odds timing) rather than writing your own heuristics.
Side effects
- No alerts returned if no fills exceed the min_usd threshold in the lookback window
- Polymarket API downtime may cause empty or partial results
- Very short lookback windows (1-2h) may yield few or zero fills
- limit values outside 1-100 may be rejected or clamped
- Network or payment errors may return a non-200 response before any data is returned
