Screen a crypto deposit for AML risk

1Call risk-score on the source address

Pass the chain and address. The risk endpoint is C3-metered, so a small per-call credit cost applies.

  -H "Authorization: Bearer sk_live_..."

2Read the score and exposure

The response carries a 0–100 score, a normalized risk_level, a confidence value and an exposure array listing the illicit categories the address is connected to and how many hops away.

> { "score": 72, "risk_level": "high",
>   "confidence": 0.86, "source": "internal-graph",
>   "exposure": [{ "category": "mixer", "hops": 1 }] }

3Route the decision

Apply your own thresholds: credit low-risk deposits automatically, queue medium-risk for manual review, and hold high-risk until cleared. Persist the full response alongside the deposit for your audit trail.

4Monitor afterwards with KYT

For ongoing obligations, send the same transfer through transaction screening (KYT) so post-credit activity keeps generating decisions without a separate console.
