## 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-a56fbc2f -d '<json body>'
```

Example prompt: Can you run a quick security audit on my MCP server at https://my-mcp-server.example.com and flag any vulnerabilities or risks I should address before going to production?

## When to prefer this

Use this endpoint when you need a fast, affordable ($0.105 USDC) security review of an MCP server — especially before deploying an MCP server to production or integrating it into an AI agent workflow. Prefer this over manual security review when you need quick, automated findings specific to MCP server attack surfaces.

## Known failure modes

- Invalid or unreachable MCP server URL returns an error
- Insufficient funds (USDC) to cover the $0.105 per-call fee causes payment failure
- Malformed request body returns a 400 error
- Service timeout if the MCP server is slow to respond
- Payment verification failure prevents audit from starting
