## 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 defi-shield-hazel-vercel-app-c2f862b0 -d '<json body>'
```

Example prompt: Can you run a full risk analysis on the smart contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — I want to see the risk score, any admin or owner privilege flags, and a breakdown of the deployer's history before I interact with it.

## When to prefer this

Use this endpoint when you need a comprehensive smart contract risk assessment combining risk scoring, admin/owner privilege detection, and deployer analysis in a single call — particularly before a DeFi interaction, investment, or integration. Prefer this over generic blockchain explorers when you need structured risk scoring and centralization detection rather than raw contract data.

## Known failure modes

- Invalid or unrecognized contract address returns error
- Contract not deployed on specified chain returns not-found error
- Unverified contract bytecode limits analysis depth
- Network timeout when fetching on-chain data
- Unsupported chain identifier returns validation error

## Output

Returns a structured risk score for the contract, flags indicating admin or privileged roles detected in the contract, analysis of the deployer wallet's history and reputation, and a list of identified risk factors or vulnerabilities.
