## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```

Example prompt: Can you run a full security audit on this token contract 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed on Base (chain ID 8453) — I need to know if it's a honeypot, what the buy/sell taxes are, and whether ownership has been renounced?

## When to prefer this

Use this endpoint when you need a comprehensive DeFi token security assessment covering honeypot risk, tax analysis, and ownership checks in a single call — especially before executing a token swap or recommending a token to a user. Prefer this over general block explorers when you need structured, agent-consumable security data rather than raw contract inspection.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty audit
- Unsupported chain ID results in a chain not supported error
- Token contract recently deployed may have insufficient on-chain data for full analysis
- Network congestion or RPC issues may cause timeout or incomplete results
- Malformed address format returns validation error
