## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability synthora-insider-radar-41523141 -d '<json body>'
```

Example prompt: Scan Polymarket for insider-style trades over the last 48 hours — minimum trade size $25,000 — and give me the top 10 most suspicious alerts with their severity scores and reasons.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
