What is a crypto fraud detection API?
A crypto fraud detection API analyzes a blockchain address and its behavior to determine whether it is associated with scams — drainer contracts, phishing campaigns, rug pulls, or fraud rings — and returns a risk assessment your app can act on. InSoBlok computes this from on-chain behavior, economic modeling, and counterparty-contagion analysis, returning a score and explainable labels in milliseconds so you can warn or block users before money is lost.

Frequently asked questions
What kinds of scams can it detect?
Wallet drainers, phishing wallets, rug pulls, wash trading, and addresses linked to known fraud rings — returned as explainable labels alongside a 0–1000 risk score.
Can it catch new scam wallets that aren’t on a blocklist yet?
Yes. In addition to known-scam matching, the API uses behavioral signals and counterparty-contagion distance, so a brand-new wallet funded by or transacting with known scams is flagged before it is widely listed.
Is it fast enough to warn before signing?
Yes — scoring returns in sub-second latency, fast enough to display a warning or block the action before a user signs a malicious transaction.
Which chains are covered?
Ethereum, BNB Chain, Arbitrum, Optimism, Base, Polygon, Avalanche, and the InSoBlok (INSO) L2 through one normalized API.
