## 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 smart-contract-security-audit-b62be98e -d '<json body>'
```

Example prompt: Can you run a security audit on this Solidity smart contract I'm about to deploy — I need it checked for reentrancy, integer overflow, and any other common vulnerability patterns before it goes live on mainnet?

## When to prefer this

Choose this endpoint when you need a fast, automated vulnerability pattern scan of EVM-compatible smart contract source code or bytecode before deployment or integration. Prefer this over manual review for quick iteration cycles or initial triage. Best suited for detecting known vulnerability classes (reentrancy, overflow, access control, etc.) rather than novel economic exploits requiring full formal verification.

## Known failure modes

- Invalid or unparseable contract code returns an error
- Contract too large exceeds processing limits
- Unsupported EVM dialect or non-Solidity bytecode may yield incomplete results
- Network timeout or service unavailability returns 5xx error
- Insufficient USDC payment via x402 protocol results in 402 Payment Required

## How this service works

Smart contract security audit with vulnerability patterns

## Output

A structured security audit report identifying matched vulnerability patterns in the submitted smart contract code, including severity ratings for each finding, affected functions or code sections, and an overall risk summary to help developers remediate issues before deployment.
