Insider scanner - 0xinsider API

Goal: catch wallets that look like they knew something, fresh wallets taking large, well-timed positions right before a move. The insider radar does the detection; this recipe drills into each flag for context. All requests need a Bearer key. See Authentication. Insider radar is Polymarket-only; see Platforms.

1. Pull the flags

Each flag has a suspicion_score and a severity of flag or watch (watch is the higher-conviction tier). Filter to the strong ones:

import os, requests

BASE = "https://api.0xinsider.com/api/v1"
H = {"Authorization": f"Bearer {os.environ['OXINSIDER_API_KEY']}"}

flags = requests.get(
    f"{BASE}/insider-radar",
    params={"severity": "watch", "min_suspicion": 70, "limit": 50},
    headers=H,
).json()

for f in flags["data"]:
    s = f["scores"]
    print(f'{f["suspicion_score"]:.0f} {f["trader"]["username"] or f["trader"]["address"][:10]} '
          f'timing={s["timing"]:.0f} edge={s["edge"]:.0f} size={s["size"]:.0f} fresh={s["fresh_wallet"]:.0f}')

The scores object breaks the suspicion down into timing, edge, size, and fresh_wallet components, so you can see why a wallet was flagged.

2. Open one flag

Fetch the full flag for its evidence and the linked trader and market:

curl -H "Authorization: Bearer $OXINSIDER_API_KEY" \
  "https://api.0xinsider.com/api/v1/insider-radar/flg_..."

3. Confirm with context

A flag is a lead. Confirm it with two reads:

flag = flags["data"][0]
addr = flag["trader"]["address"]
cond = flag["market"]["condition_id"]

trader = requests.get(f"{BASE}/trader/{addr}", headers=H).json()["data"]
intel = requests.get(f"{BASE}/market/{cond}/intel", headers=H).json()["data"]

print("trader grade:", trader["grade"], "| markets traded:", trader["stats"]["markets_traded"])
print("smart money net flow:", intel["smart_money"]["net_flow_usd"], intel["smart_money"]["direction"])

A fresh wallet with a high size score, taking the same side smart money is leaning, is the pattern worth a closer look.

4. Cross-check size

Confirm the position is large in absolute terms with large positions, filtered to the same market:

curl -H "Authorization: Bearer $OXINSIDER_API_KEY" \
  "https://api.0xinsider.com/api/v1/large-positions?condition_id=0x123...&min_size=25000"

Position.trader.is_new_wallet and wallet_age_days are the fresh-wallet signals to confirm the radar’s fresh_wallet score independently.
