## 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`):

```sh
zero fetch --capability gentech-defender-classifier-cfd59f9c
```

Example prompt: Can you run a Defender classification on the address 0xAbC123...456 on Base Network to see if it's flagged as malicious or risky?

## When to prefer this

Use this endpoint when you need fast, pay-per-call on-chain security classification specifically for addresses or contracts on the Base Network (chain ID 8453). Prefer it over generic blockchain explorers when you need a structured threat label or risk classification rather than raw transaction data. It is well-suited for pre-trade checks, wallet validation, or DeFi integration safety reviews on Base.

## Known failure modes

- Invalid or malformed address returns an error or empty classification
- Address not indexed on Base Network may return no result or unknown classification
- Payment failure (insufficient USDC balance) results in 402 response and no classification
- Rate limiting or network timeouts may cause request failures
- Non-Base chain addresses may return irrelevant or null results
