answers 402

Fast wallet risk check for any EVM address or ENS name using Web3 Antivirus quick-scan. Returns in ~350ms — ideal for real-time pre-transaction screening. Returns a toxic score and which risk flags fired. Use shouldFlag to block or escalate: any non-zero score means the wallet triggered a risk flag such as sanctions, scams, mixers, or phishing. Roughly 27x faster than the full scan endpoint.
