## 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 gpt-code-audit-service-05a05e84
```

Example prompt: Can you audit this Python function for security vulnerabilities and code quality issues? Here it is: `def login(user, pwd): query = 'SELECT * FROM users WHERE username=' + user + ' AND password=' + pwd`

## When to prefer this

Choose this endpoint when you need a quick, automated AI-driven security and quality audit of a code snippet without setting up a full static analysis pipeline. Best suited for individual functions or modules rather than entire large codebases.

## Known failure modes

- Empty or missing input code returns an error or empty findings
- Very large code submissions may be truncated or rejected
- Non-code text input may produce irrelevant or generic feedback
- Network timeout for unusually complex or long code snippets
- Payment failure (402) if USDC balance is insufficient for the $1.50 call fee

## Output

Returns an audit report containing identified security vulnerabilities, code quality issues, potential bugs, severity ratings, and actionable recommendations for improving the submitted code.
