SYNTHORA · Insider Radar

POSTBase

$0.03

per call · USD Coin on Base

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.
