WalletScreener is a REST API that risk-scores any blockchain wallet address. One call gives you: a 0-100 risk score, OFAC sanctions screening (auto-refreshed from Treasury SDN list), behavioral pattern detection, ERC-20 token forensics, and cross-chain correlation across 6 networks. Plus historical tracking, webhook alerts, and PDF reports. Built for compliance teams, exchanges, and DeFi protocols. Free tier available — no credit card. Paid plans from $99/mo. Try it at walletscreener.io

Hey PH! I'm the maker of WalletScreen. We built this because every exchange and DeFi protocol needs to screen wallets for sanctions compliance and fraud risk, but the existing options are either $50k/yr enterprise contracts or sketchy free tools. WalletScreen is a simple REST API: pass a wallet address, get back a risk score with labels explaining why. It checks OFAC sanctions, analyzes transaction patterns, scores token holdings, and works across 6 chains. Free tier available — grab a key and try it: https://walletscreener.io Happy to answer any questions about the scoring methodology, compliance use cases, or the tech stack.
