At 20 checks/day, saves $5.40/day ($162/month). Call this endpoint BEFORE interacting with any unfamiliar smart contract to get a 0-100 risk score. Returns identified vulnerabilities (unverified source code, proxy upgrade risks, admin-only functions like mint/pause/blacklist), deployer wallet forensics (transaction history, scam flags), contract name, and an actionable recommendation (LOW_RISK/MEDIUM_RISK/HIGH_RISK/CRITICAL_RISK). Use this to avoid rug pulls, honeypots, and unsafe contracts. Costs $0.50 per call. Average rug pull causes 96% loss. A $0.50 contract risk check on a $5,000 trade has potential ROI of 6,240x.","params":{"address":{"type":"string","required":true,"description":"The 0x smart contract address to analyze"},"chain":{"type":"string","required":false,"description":"Chain to analyze on (default: base)"}},"exampleRequest":{"address":"0x1234567890abcdef1234567890abcdef12345678"}}
