One API call to screen a wallet, a transaction, or an entire threat actor.

REST and webhooks, native SDKs in five languages, and authentication built for regulated environments.

Quickstart

Screen your first wallet in one request.

Base URLhttps://api.cygy.io/v1

Every screen returns a risk_score, risk_category, matched_labels, sanctions_hit, and entity_cluster — within 200ms.

screen-wallet.sh

curl -X POST https://api.cygy.io/v1/screen/wallet \
  -H "Authorization: Bearer $CYGY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "address": "0x9f2e…a1c4", "chain": "ethereum" }'

# → 200 OK  (returned within 200ms)
{
  "risk_score": 0.91,
  "risk_category": "high",
  "matched_labels": ["mixer", "sanctions_proximity"],
  "sanctions_hit": false,
  "entity_cluster": "cluster_8821"
}
