## 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 api-the402-ai-81c9a534 -d '<json body>'
```

Example prompt: Can you kick off a security audit for my MCP server — the service ID is svc_975404aece3a44c5 — and let me know the job ID so I can track progress?

## When to prefer this

Use this endpoint when you need a professional, automated security audit specifically for an MCP (Model Context Protocol) server and are willing to pay $1.05 USDC per audit. Prefer this over generic code scanners when the target is an MCP server powering AI agent tools, as it is purpose-built for that stack. Choose this when you need a job-based async result you can poll later.

## Known failure modes

- Missing or invalid 'id' field returns a 400 validation error
- Unknown or unauthorized service ID returns 404 or 403
- Payment failure or insufficient USDC balance causes transaction rejection
- Service temporarily unavailable returns 503
- Audit job creation fails internally, returning a 500 error with no job_id
