Example: {\"address\":\"0x6B0F4651eD42893ab58139938175E4a69f175F25\",\"chain\":\"base\",\"kind\":\"token\"} — chain defaults to \"ethereum\" and kind defaults to \"token\" if omitted, so a call can be as small as {\"address\":\"0x...\"}. Use POST /api/explain instead when you already have a specific approval/permission JSON payload (from a scanner, a dapp prompt, etc.) and just want it translated to plain language, without an on-chain lookup. Both return {verdict: SAFE|CAUTION|RISK, explanation: string} so downstream agents can branch on verdict without parsing prose."
