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. Each alert carries wallet, market, size, tx hash, a 0-100 severity score and explicit reasons; approximations are declared in the methodology field. For prediction agents tracking informed money. No charge on service failure. Ed25519-signed. $0.03 USDC per call via x402 on Base. Free trial: 3 calls per wallet with header X-WALLET.
Output
Returns a JSON object with a list of trade alerts, each containing the transaction hash, buy/sell side, trade size in USD, price, market identifier, wallet address, predicted outcome, severity score (0-100), human-readable reasons for flagging, market 24-hour price change, wallet historical trade count, and market 24-hour volume. Also includes aggregate metadata: total fills scanned, lookback window, minimum USD threshold, and a methodology description.
Example use cases
Monitor smart money before major event
“Check the last 72 hours of prediction market fills for trades over $50,000 and show me up to 30 alerts — I want to see if any fresh wallets are loading up on a specific outcome before a big news event.”
Daily briefing on suspicious market activity
“Give me today's insider radar summary — look back 24 hours, minimum trade size $10,000, up to 25 alerts — and highlight anything with a severity score above 70.”
Screen for high-conviction whale positions
“Pull the insider radar for the past week using a 168-hour lookback, trades over $100,000, and give me the top 10 alerts so I can see which wallets are making the biggest informed-looking bets.”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/insider-radarWhen to prefer
Choose this endpoint when you need to surveil prediction market order flow for anomalous or potentially informed trading, especially from fresh or low-history wallets making large moves. It is more specialized than generic on-chain analytics tools because it combines wallet history, trade size, and market momentum into a single severity-ranked alert feed purpose-built for prediction market insider detection.
Side effects
- Invalid limit value outside 1-100 returns a validation error
- lookback_hours exceeding 168 may be rejected or clamped
- No alerts returned if no trades meet min_usd threshold in the lookback window
- Payment failure (402) if USDC balance is insufficient for the $0.03 per-call fee
- Network or infrastructure timeout if the on-chain data source is slow
