## 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

Example prompt: Can you run a comprehensive security audit on my smart contract at address 0xAbC123... on Ethereum mainnet and give me a full vulnerability report before we launch?

## When to prefer this

Choose this endpoint over the basic scan sibling when you need a comprehensive, in-depth security audit with full vulnerability detection rather than a quick safety score. Ideal for pre-launch audits, investor due diligence, or high-value DeFi protocols where thorough analysis is critical. This is the premium tier audit versus the basic scan.

## Known failure modes

- Invalid or unverified contract address returns an error
- Unsupported blockchain network not recognized
- Contract source code unavailable or not verified on-chain
- Malformed input contract code causes parsing failure
- Payment of $1000 USDC not received results in 402 rejection
- Timeout if contract is extremely large or complex
