The NZOChain REST API lets you embed real-time Web3 threat intelligence directly into your product. Use it to scan wallet addresses for malicious activity, detect dangerous token approvals, monitor on-chain behavior, and trigger alerts before your users are exposed to harm. Whether you’re building a dApp, a non-custodial wallet, a DeFi protocol, or a centralized exchange, the API gives you the signal you need to act.
