## 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 achilles-code-audit-bff99944 -d '<json body>'
```

Example prompt: Can you audit this Solidity smart contract code for vulnerabilities before I deploy it? Here's the code: [paste code here]

## When to prefer this

Use this endpoint when you need a quick, paid AI-driven code audit — particularly for smart contracts or agent-economy code — before deployment. Useful when you want automated security validation without setting up a full local auditing toolchain.

## Known failure modes

- Missing required 'code' field returns validation error
- Unsupported language may produce generic or degraded analysis
- Very large code submissions may be truncated or rejected
- Payment failure via x402 returns 402 status with payment instructions
- Malformed JSON body returns 400 bad request
